I’ve experienced anxiety and low self esteem for a few years now, it has always effected me in different ways, however now it’s starting to impact my social life. I have never actually spoken to anyone I know about this as I have never been formally diagnosed, but friends have said to me that they think that I am struggling with these issues.For as long as I remember I have always been self conscious of my looks, but as I have got older, it has only gotten worse. Insecurities that I rarely thought of are now at the front of my mind all day, every day. I get invited out to parties at the weekends and will confirm that I am going to attend, yet the night before I always find myself in tears over the stress of going. I don’t want anyone to see me looking the way that I do, I’m always questioning how someone as bad looking as me can even get invited to places. My friends think I am rude for cancelling plans always last minute but I cannot explain to them the way I am feeling. I begin to question whether my perception on the world is even remotely accurate- I feel as if I see things completely differently to everyone else.As far as I see myself I am a so ugly and cannot see my life getting any better unless I change the way I look. I get embarrassed when talking to people just because my appearance. It sounds so easy to say but impossible to change the way I’m thinking- because I know what I see. I’m only 17 years old and feel like I am literally ruining my own life by excluding myself and constantly worrying.
I think you should keep a gratitude journal. Having good friends and being invited to parties is something to be thankful for. My friends daughter sat home most of her days in high school and didn’t know why she wasn’t invited any where. I also think you should volunteer (anywhere) or even just help another student with their homework/study for a test. Doing things for others will keep your mind busy so your not focused on yourself. You can even do something for yourself such as organizing your bathroom drawers or even closet—When you are doing something good it makes it better.
Hi, Lucy
Firstly…well done for talking about it and you’re not alone. It’s taken me over 60 years so you’re way ahead! And it’s OK 
Your local library should have some books you can take out : The shyness & social anxiety workbook for teens , by Jennifer Shannon is one I’d mention - I found it helpful & refreshing too with lots of examples similar to your feelings and experiences.
Your local NHS mental health team & local Doctor may also have suggestions for courses run to address anxiety. : I didn’t know about the help until it was mentioned to me. I now know that anxiety is perfectly normal…until it stops you doing what you want to and I have learned ways to help cope with it.
Finally, have a look online at the charity Young Minds which you may find a good starting point.
Good luck and don’t give up.!
