First off, I don't have Bpd, I just came across this page through google searching something else and just from what I know about bpd symptoms I think this is something someone who has it would be able to relate to. 

because I've felt depressed for so long, doing nothing, its made me feel like I don't have a real personality. So I feel stuck between leaving my depression and venturing out into the world and socializing with people and feel like I'm faking everything, or keep it wrapped around me like a warm blanket and not have to question anything about myself. 

It sucks but because I was depressed for so long I feel like its become me and if I try to act different people will call me out for being a phony.
