Feeling depressed after bad critique on my drawings. Advice please?

I'm 13. I'm in 8th grade. I'm enneagram type four. I've been known for totally bashing on myself when I do the wrong things. sometimes I start to cut myself (three scars on my wrist? I think I'm about to make it six... hope not...) I've been known for not being in the state of happiness and I was in a rut in the beginning of the school year. I hated myself for not being popular when everyone around me was. I felt imperfect. I felt I never belonged. I felt the world was such a super dark place and all of that. I was definitely in a rut, and I feel like I'm about to go back in it. I've always felt imperfect. there's this side of me that i feel is over hyper and annoys people, and i really wanted to control it. I use to hurt myself with a rubber band just to chain it. I don't do that anymore and I have gotten better at controlling it. There's this super depressed side of me that acts when I'm left alone. I don't talk. I can't do anything right. I hate and bash on myself the most. but it's also in this stage where I think a lot. My brothers, sister, and uncles have tried to help me a lot and they've told me useful things that I just can't carry out. I feel everyone hates me and I have no self significance. I have a lot of friends and my brother's so popular so some of his friends talk to me, but I can't say I got friends that will help me get over sad stuff completely. I could commit suicide right now and no one would cry when I know that that's not true. everyone says I have a dream life. my family is really rich. but what good is a 9 chaired movie theater with projector and 144sq in. screen when you lose your ability to live? I was having an awesome day today, until I read some critique on my drawings (deviant art account: animemefreak74). I never thought they were pro and I really wish that someone could help me out because there are so many things I'm not clear on. Before I began drawing 7 weeks ago, I totally felt insignificant and I had no self significance. there was nothing good about me, a lot to hate about me. drawing made me feel a lot better. Hearing this, I've lost my ability to carry on. I have been in a drawing rut for almost a week due to lack of practice. now I just, the future that eventually everything would improve and that I'd be able to draw great things has gotten so blurry now. I lost the ability to believe in myself. I can't live. I don't want to do anything. can't even practice. I'm drowning in a pool of failure and I need help to get out.
