I'm 16 and I feel like I have depression but I have no idea what to do. Its happened over the last few months as I had developed bad IBS and that had me feeling low. Then a family member recently died and I now don't want to speak to my friends or boyfriend, I have got an extremely low self esteem (ugly, fat, a waste of space), I have no energy anymore, I hate myself, I don't want to try because I feel like I fail everything, I feel sick a lot of the time, always negative and I've been having bad thoughts and actions (self harm).
I haven't told my parents because they think I'm overreacting about everything and an attention seeker, I love my parents but I think they don't want to talk to me.
What should I do?
