look i have depression so listen to me , avoid and ignore all the people who bother you or try to put you down, do not hang out with people who are fake to you, try to make less friends that you trust, having 1 friend is better than have 20 fake ones. always watch videos that make you happy. try to not watch a lot of sad things, ignore all the hatters and love yourself, get a lot of rest and eat healthy and exercise and the most important thing is be confident and love yourself :)
