HOLY CRAP that is a lot of meds. I'm not condemning you just be careful. It is really best to do tapering off meds under a doctor's supervision, some of them can have really horrible side-effects. They typically don't do ECT for bipolar disorder, so that strikes me as odd, as well as your T calling you a "pathological personality." You might think about whether or not you want to keep seeing those particular professionals, if you don't think they know what they're doing?

Have your husband watch for manic behavior. If you are indeed bipolar then the Lamictal may or may not prevent that by itself. You sound well informed so I assume you know what to tell him to look for. I take Welbutrin and Nortryptiline for my depression and anxiety, they don't really help BPD because it can't be treated with meds but the Nortryptiline helps take the edge off so I can better regulate my emotions. I didn't know I was really, really, really angry until I started taking them. It gives me the ability to stop and take a step back that I definitely did not have before. I believe that we have a biological predisposition to PDs and it's triggered by our environment. Research is backing that up, btw, so don't feel bad if it turns out it's not entirely organic. Look into DBT skills, if you haven't already. As you feel less tolerant, the emotional regulation can definitely help.
