I can totally relate to not wanting to accept the diag. I tried to self medicate for years and it just made my life worse. It wasn't until my 3 time being diagnosed with Bipolar did I actually accept it.
Just because you accept it, doesn't mean it's a bad thing. You can accept it, read up on it and still live a great life.
I know about being manic because I was just manic a few weeks ago. I felt like I could do anything, I had a ton of WONDERFUL ideas and didn't require as much sleep. It was only because I have educated myself on Bipolar, did I recognize I was manic. For the first time ever, I was able to recognize it.
I hope you can trust your Pdoc and let the meds do their jobs. You will feel much better once you are stable.
Good luck to you!
