I really need help with my friend! she keeps on talking about how depressed she is and it is really getting on my nerves but she is also freaking me out because she has self-harmed in the past and i think she is getting back into the habit because whenever she is frustrated, she starts scratching herself and she sometimes starts cutting herself with scissors or her compass and it is really scaring me.

she is also making me worried because she always says that her class is stereotyping her and she is very sad about it but it has made her want to move schools and she has started applying to some other arts schools but i am very worried that if she moves, i might not ever be able to see her again and i won't be able to stop her from doing something really stupid.

she is really frustrated and says she hates her life and at our sleepovers, she is either screaming in her sleep, saying things like 'no, stop it, please, just stop' or just not sleeping at all. i hate her doing this and i need help because after going through all of this with her, i'm not sure if i want to be her friend anymore because she is bringing me down and every time i talk to a counceller about it, i end up in tears because i don't know what i'd do without her. i'm on the brink of crying now so i'm going to stop.

what should i do?
