I wonder why我的疑惑

I feel so tired these days.Or can say I am suffering from loneliness.This is my biggest problem.I wonder why every body can't understand me .I am not a strange person.Maybe I do something wrong,but can you tell me why?
Nowadaya,I thougt a lot of things .However ,I couldn't find something wrong.I love all of my classmate.
