Shes my best friend and then she's not?

Okay sometimes friends have different interests like i love to read and all my friends hate it! But as long as you make the effort to support eachothers interests then things should be fine. but if she isnt being supportive or trying then maybe its better to look for friends elsewhere. Maybe if you cant find any at you school join a club or something outside of school and meet ppl with the same interests as you. As for the being suicidal thing dont even think that. Suicide is serious and if your seriously considering seek help now. Good luck hope everything works out!
