Welcome to HealingWell and the Bipolar Forum. It is great to have you here!
When I first started attending therapy on a regular basis more than 5 years ago, I was a mess. I would go and beat around the bushes with everything, and would be super anxious before as well as during the session. But then I learned that anxiety is common with people who have bp, and I dont let it hold me back anymore.
Now, I try to make therapy a big part of my life, but have been going as much as I should lately. It keeps me in check, so that my symptoms don't get out of control. Plus it is a good place to get rid of stress from daily life and to talk to someone who is a neutral party.
I have gone through a few therapists in the last couple of years till I found the right one, and it was a stressful moment. And 2 weeks ago I learned that my current therapist is leaving, I freaked out a little. But have not come to accept it. Change is good and it is a part of life.
Good luck and please let us know how things go.
