I'm a bit late to the game on getting help. I'm in my early 40's and was just diagnosed with BPD today. 

A couple of months ago I was diagnosed with  Bipolar 1. This is on top of fibromyalgia, lupus, endometriosis, chronic migraines, and a host of other medical issues. Oh, plus I have 2 kids to take care of. One teen and one with severe autism, deafness, and developmentally disability. FML

Pdoc says my bipolar is stable so this "please kill me now" feeling must be pure BPD.
