Hi, from what you've said, it certainly sounds possible that you have BPD. I can't be certain, but then, neither can doctors, bcoz BPD is very hard to diagnose.

I recognize the symptoms because they are like my own, so that's why I feel you have it.

Some honest advice: don't put too much emphasis on the label BPD. Instead, try to work on the individual symptoms, one by one, finding coping mechanisms or fixing the problem if possible.
