Hi Jessica. So glad you found a place to share your thoughts. It sounds like you've already done some research on this, but here is a link with loads of info on BPD:

Are you a college student? If so, have you checked out the school's counseling center? Getting in-person help really is the key. Having lost your dad at such an early age is a very big deal. On top of that, to have relationship issues - well, you just really need someone to talk to about all this. In person!
My mom died when I was about that same age. I waited much too long for therapy. The sooner you talk to someone, the better your life will be in the long run. Truly. To learn how to deal with that grief, and to better handle your relationship issues *now* can improve the rest of your life. :-)
Do listen to all us wise ladies and gents - we've been there!
Take care. Emmy
P.S. Feel free to PM me any time.
