I would not put a ton of faith in an online test though the ones for depression are pretty accurate I think, personality disorders I think are best left to professionals. If you are not seeing someone for individual therapy I would recommend it, I see one and she helps with dealing withh every day stresses, things that are bothering me a lot, like what is bothering you now, and helps keep an eye on my mood states because sometimes she can see a manic or depressive mood before I do. She does a therapy called cognitive behavioral therapy (cbt) that can also help with anxiety. Your ex friend sounds very immature and like someone you may be best rid of but I know it hurts to lose a friend and to have someone yiu trusted hurt you like she has. You have every right to be hurt and angry. But try to do something good for yourself that makes you feel good and try not to let the hurt fester in you. Write it out on paper if you need to, that helps me. I can say everything and every curse word I want to on paper then shred it or cut it or whatever. Anyway that is something I do. I hope this helps some .
