well i would say that your actions are symptomatic of bpd. and bpd and depression are not mutually exclusive. if that is the dx you've been given you might just have to live with it. yes there is some stigma and some crappy doctors who will treat you differently but there are many who won't, like the nice psychiatrist you met at the hospital! also there is a lot of evidence to suggest that bpd is very treatable so you should find someone who believes that and work on getting better
