I have always felt alone till now

In my whole life I felt Like I couldn't trust anyone like I was alone I didn't know what to do but to fall in love with this guy who was not so much a guy he was not human but I still fell in love with him.I did not know what to do I wen't to the darkness but it felt so good to be with someone who knows what it feels like to feel this way.My whole life I didn't know how to listen my ex-boyfriend he cheated he cheated on me with someone I really cared about my best friend but now she still tries to become my friend again but I can't trust her anymore I don't know who to trust because of everything that's happened then I met someone that changed my world he rocked my world then he bit me.
