Wow, Im just really glad this is here. Thank you for existing. 
I was diagnosed with BPD a couple months ago, and it was like a light switched on. It explained SO much of my life. I'm going through an especially rough patch and was hoping to find a way to talk to someone about this. I can't believe I didn't think of Reddit sooner. I don't know how active it is here but I am going to start lurking and maybe posting sometimes. 

So...hi.
