Life is unfair. My girl has been talking to my closest friend behind my back

 
I dont have a friend to call best friend. 

I dont fit in.

Its just like there is something the others understand or do that makes them fit in.

I can count my friends with 1 hand

I dont even know if my parents love me
Everytime i do something im proud i did its like the get dissapointed

I get good grades but they are dropping cause i get 5 hours of sleep every night

What is wrong with me?
