Hello, stillquiteyoung, and welcome to Psych Central! I have Bipolar II and have been told by my psychiatrist that I have had mixed states. You do need to be taking some sort of medicine(s) to help keep you stable. If lithium doesn't work for you, then there are other possibilities. Also, I can tell you aren't happy with the doctor you were going to, so please seek out some other professional who can help. As you see, life is miserable when we don't get and stay in treatment. Okay?
A professional is the only person who can really say what you are experiencing, too.
