Dear Bella
as I read your description, I felt you are talking somehow about me, I was stuck on the intenet for thousands of hours trying to figure out what is wrong with me and what is it called
I had consulted several psychiatrists over years, and like you i started with sertraline,
I dont know a lot about BPD, but i think black and white thinking is a major diagnosis creteria
but about pibolar, it is devided into three (or even more) catagories, and from your descriptions It might be cyclothymia or rapid cycling what you are suffering from.
it is usually treated with AD with a mood stabilizer, and sometimes atypical antipsychotic, they are somehow effective, but I think psychotherapy is very essential too, unfortunetly I never had the chance to try it.
if you googled cyclothymia you can read more about the subject.
I think you should get back to the doc and tell him how you feel, if he didnt respond try talking to someone else, like a parent so you can get proffesional consulting.
hope you will get bettre
