I've been just so depressed for the past month, advice needed

For the past month i have been feeling just extremely sad. I have had an onset of these feelings since september last year, but now that summer has come it has reached a new level. My relationship with my family is destroyed, i feel constantly angry at them, shaking off offers of help but feeling incredibly hurt and lonely when i can see them visibly avoiding me and staying out of my way. I also suffer from bulimia which just fuels my mood swings and low-self esteem. It is all cosuming. I am a dancer, but find little interest in training at the moment, with little tasks seeming so overwhelming i feel suffocated. Siblings tell me to stop crying because i am 'so privaledged, there are children dying in Africa'. I know that fundimentally, i must be acting extremely selfishly, but i just want my life back. I used to be a happy person, but just see no direction anymore, just guilt, anger and intense, intense sadness.

Jo I think you could do with some professional help? I suffered so bad and would not wish anyone to go through it alone. Ask me anything and I will try to be of  help

How did you know it was worth going to the doctors for? I basically feel sad all of the time, just extremely unhappy and negative about everything. I want to do something but am skeptical about the fact that maybe everyone feels sad? I feel alone and constantly think / dread the idea of me having to live for another how many years. Especially if it's all going to be like this. I also  aware of how whiny and attention seeking I sound which is another reason I hesitate to go to the doctors for 'medical' treatment which I'm afraid they will pass off as '19 year old girl self absorbed troubles'

Hey jo, feeling pretty how much you do, 20 now and my family pretend like they get it but eventually tell me things like im being selfish and should grow up and take some responsiblity. Dont think like you are whining, you can't help how you feel and maybe it helps you get things out sometimes.

I can't really give advice about the doctors as i am yet to even go but i would hope they would be able to help us, they certainly wouldnt pass you off as just someone with self absorbed troubles. How long have you felt like this ? x

I am starting to write a bit of a diary about how i feel everyday and write down and try and figure out the thoughts that can lead me to just laying in bed for days really upset, might be worth trying!
