Hi, darkgambit, and welcome to Psych Central! You are certainly free to talk to us and to continue to do so after you see a therapist. (I see a therapist and come here, too.) We do understand all the things that can happen with bipolar. You can get to know us!
I have Bipolar II and also Generalized Anxiety Disorder.
Since you are new, I also suggest you join our two bipolar social groups. We also have a weekly chat time. Members can join groups and chats after they get five posts approved. Here are the links to the lists:

Again, welcome!
