If you're therapist makes you uncomfortable then find a new one! I had a therapist who I didn't click with, we just always seemed to be talking at odds and then he got a perm. And it looked weird. Like Steve from Bloom County comic strip in his "Alan Alda" phase. I could barely look at him, luckily he knew things weren't clicking and suggested someone else.

If you want to "break up" with your therapist there's the , "It's not you, it's me" version, "I'm not sure why I but I really don't think we are clicking and I need to find a new therapist." Then you can see if he has recommendations or look on your own.

There's the truth, "You remind me of my father and therefore it's really uncomfortable for me to open up to you, I'd like to find another therapist."

And then there's the way I have handled things - leave and never go back without a word. "Um, my schedule is kinda weird so.... I'll call and schedule." or if it's scheduled either 1) don't show up (this usually costs money I don't advise it) or call the office and let the front office person know you are cancelling "I have to cancel and I'm not sure when I can reschedule. I'll call back".

Or call and leave a voicemail that 1) you are cancelling the appointment or 2) you aren't coming back.

If he makes you really really stressful I'd go with either cancelling the appointment or leaving a message.
