I'm really sorry.

it really is sad that ppl treat ppl with bpd that way. Just know it's out of their ignorance. My borderline traits have calmed as I've gotten older. But at one time I thought I was just borderline and even some counselors treated me like crap sometimes. It's really unfair. What I've learned to do is just slowly get to know ppl. Then build up trust and just let them in a little at a time. I'm sorry u feel so alone. I do too sometimes.
I hope u get to feeling better.
