How to have a realationship

I'm 21. And I have nothing. 
I sort of have a boyfriend of 5 1/2 years. But he does everything to push my buttons and drive me crazy. He calls me names all the time.. And sometimes tells me he wishes I wasn't here. 
I have no one to talk too. 
I wish I could have a normal realationship with anyone. 
But I'm stupid. I'm useless. No one likes me. 
I'm going to lose my mind. No one loves me. 
I have no one to talk to. And I'm sick and tired of this useless life. 
I'm done. I can't take one more minute. 
I'm done.
