Stay honest, he can't help you thoroughly if you keep things back. Also, you are paying him for his services,he's there to help you, not be a friend or relative.
You'll get more out of your therapy if you do not hide things, don't feel embarassed,don't feel he'll punish you, he needs to be able to help. If it's something irrelevent to your therapy, he'll tell you. I said to my former, on my first visit, "Okay, where do we start? What do you want to know?" He exclaimed, he wasn't doing therapy like the stereo typical scene, patient lieing down on a couch as people most picture therapy like.
We sat in his living room and chatted, he sat across on a chair and I on the other side on a leather couch,propped in the corner end. When I moved out of state, I went to a clinic, and had therapy with a lady in her office room. Either way, I was honest with what was going on or wasn't, and then we were able to work on things, some a few steps at a time.
I wish you lots of luck, and encourage you to give it a try.
