I'm 16. My mole on the lower back started to hurt if I touch it. There is also a red ring around it and it feels a bit hard to touch. It's dark-brown color and it is circle-shaped. I know some symtoms show to melanoma and I'm wondering if it could be something else or am I dead 
O que você está descrevendo pode ser câncer de pele. Não corra riscos. Vá ver um médico, ele provavelmente quererá fazer uma biópsia. Boa sorte.

If you're only 16 though, then it's unlikely to be melanoma, but melanoma is usually curable anyway.
Yeah, I turned 16 two days ago and now I'm wondering if I will even make it to 17. Here is a image, it's about 5mm big.
That pic isn't in focus, so it's hard to figure out what it might be, but it's something I think you should see a doctor about. It's probably nothing serious though, and I'd be surprised if you don't make it to 77.
Yes I will go to doctor, but is there even anything else than cancer that could make it sensitive to touch.
All sorts of things - ingrown hair, sebaceous cyst, insect bite... I don't think sensitivity has anything to do with likelihood of cancer btw.
If you could post a better pic, that might help us suggest what it could be.
Pode ser muitas outras coisas além de câncer. Pode ser estresse, alergia, picada de inseto, escabiose, infecções ou condição de pele. Tente não se preocupar e não toque nisso. Você provavelmente vai viver até os 100 anos. Vá ver um médico.
I'm seeing doctor very soon, but I'm really scared. My mole is sensitive to touch and it appears kinda lumpy, which is common for melanoma as I read. It's even color and round shape but that doesn't matter because there are already things that can be linked with cancer. Doctor will know the best, but even there, my doctor won't be able to tell me what it is (based on my experience), she will probably ask me if it hurts and because I will say yes, she can think it's serious. I will be sent to dermatologist (and I will need to wait few days-weeks) and there he most likely won't know either, he will sent me to some tests which you need to wait a couple of months so my summer will be in fear. My life was never easy, now it's going worse and worse, sometimes I ask myself what do I even live for.
That last sentence is worrying. I'd talk to the doctor about that as well, as it sounds like you may have anxiety or depression.
I really don't think the mole is anything to worry about, but if you could post a better pic, that would help us offer advice.
Sim, eu também estou preocupado com a última linha que você escreveu. Tenho que concordar com o GeorgeCap. Você deve conversar com seu médico sobre como você se sente. Você definitivamente deve se preocupar com ansiedade e depressão. Você pode ficar surpreso com a forma como elas podem causar uma série de doenças.
Why I feel that way. Nobody likes me, nobody, my parents argue all the time and then they like me even less. I don't have siblings, I don't have friends, I've been bullied in school. I'm ugly, my family is poor and we live in old house. Everytime I step into some modern house I see how beautiful life can be. You might think that it isn't that bad, but it is, I don't even have my own room, for 16 years. I have no activities except gym alone, if I didn't go there I would probably be dead already. I don't need professional help because I don't even have money and they can't make friends for me or bring joy in my life.
Oops, this is my second account, I guess I logged in with the wrong one
Parece um caso clássico de depressão. Você acha que ninguém gosta de você, mas eu vejo muitos aspectos positivos na sua vida. Primeiro, você é jovem e realmente pode construir a vida que merece. Você vai à escola, à academia, tem comida para comer, tem um teto sobre a sua cabeça e está vivo, jovem e parece estar em relativamente boa saúde. Qual é a sua definição de feio? Além disso, amigos são muito superestimados! Você é o seu melhor amigo! Você acha que as pessoas não se importam, mas você precisa se comunicar com alguém; sugiro tentar algum professor da escola em quem você confie ou talvez um treinador da academia. Você já está fazendo algo ótimo ao se manifestar aqui. Foi bom de sua parte escrever o que está te incomodando.
Desejo o melhor para você!
Ok I will use this account now. Thanks for reply. I don't really feel depresed, but because I'm not a social person this makes me sad/angry sometimes. I'm afraid what will others think if I do something and stuff. I like my own company, reading books, watching movies, playing games, sometimes it would be good if I went outside with my friends, even my parents would be happy that I hang out with others, but I just can't make friends, most of students in shool do drugs, smoke or cause trouble, I'm not that type. I don't trust gym coach I'm terrible at school sports. Ugly because I have pectus excavatum (hole in chest) that's why I also started going to gym and because I'm very tall and skinny. I don't go to beach, hell if someone saw me without shirt, they always stare at you. Overall I could say I lack of self confidence, because of my look and personality, at least on internet I don't appear ugly.
Não há nada de errado em ser introvertido. Todo mundo no mundo é diferente. Você parece ter uma baixa opinião de si mesmo e sua visão do que é feio. Você realmente precisa começar a se concentrar em todos os pontos positivos que tem. Você escreve e se expressa excelentemente, gosta de ler e de livros, parece ter valores muito bons, parece muito gentil e cuida de si mesmo. Você deveria se tornar um pouco mais autoconsciente. Vejo tantas coisas boas que você tem acontecendo. A única coisa que eu sugeriria é que você se force um pouco a interagir com os outros. Se estenda um pouco mais. Sua visão do que é feio, do que os outros pensam, é preocupante; "Tudo isso está na sua cabeça" APENAS. Você é muito inteligente, de fato, você respondeu seu próprio problema na sua última frase.
Eu quero que você tenha uma vida feliz. Compartilhe sua inteligência, bom caráter e insights para ajudar os outros.
I'm still alive. It's been two months and this mole is pretty much the same. I've got a better photo of it, it this might help.
Did you see a doctor? Both about the mole and what seems to be depression?
No, I didn't. I've been to doctor about something else with my skin, then I went to dermatologist, and he said I will go to some tests. It's been a year or more and they still didn't invite me to this tests. So if I went to doctor I would have to wait again and I would be dead before I come to these tests. About depression I won't lie I have problems, but nobody can fix that. I don't cry, I don't do drugs, smoke I don't cut myself to hide pain so I don't hurt me or anyone else. And psychologist is very expensive I don't have that much money.
Você realmente precisa de ajuda, GeorgeCap. Você realmente precisa procurar alguém que possa diagnosticar e colocar você no tratamento correto.
