Ayesha.....sorry I just now got around to reading this thread.
I'm sorry that what your T. has suggested has got you in such a frenzy. I can't really tell from your posts if you do or don't want the diagnosis. In the beginning of the thread, you sounded frantic and equated bipolar with being crazy. Later threads, it sounds like you're over-analyzing everything you say and do like you're trying to fit the bipolar diagnosis. Don't stress yourself out so much...so what if you do get "the diagnosis". It doesn't change who you are as a person. And we all like/accept you as you are.
Have you read the article "Multiple Diagnosis Labeling With PTSD" on this site? If not, you should. I felt alot better after reading it. I had been thinking "man, I'm a fruit cake." Then when I read the article, I thought, nah, I just have PTSD. You may think the same after reading it.
