Same ending different person

It's the same thing different person
They get close and pretend to be my friend
Then in the end they fuck me over
They leave me like I meant nothing to them
But to me they meant everything
I get fooled into thinking I'm their best friend
I'm tired of being treated like shit
When I do everything to be their person
Why does this always happen to me
I don't deserve this
When will it get better
