Well not completely, I’m not THAT naive. But I just need reassurance that traumatizing situations and people in the past will stop haunting me. I’m 22, and all my life I’ve had boy problems. I’m either thinking about someone else from the past, or just sulking about someone I’m with. I overthink every good thing that happens, and I ruminate about the hurt or loss I’ve felt. 
Someone please tell me I’ll think about my worries less, in time. 
If there’s any readable material/advice out there, I need it really badly. 

How ironic of a bpd, to ask for reassurance on the internet because they are feeling unassured in real life. Being vulnerable irl is terrifying.
