I feel almost exactly like this, and I understand what you mean

so you're not alone in this.
I'm not very good at giving advice, so I'll tell you what I decided to do instead: change therapist. If it doesn't work after 6 months then it's probably just not a good match - especially if you yourself can't be too open with him. It's not anyone's fault, sometimes it just goes like this.
Unfortunately I'm still looking for the next one, so I can't tell you if it worked or not. But this is what I'd do in your place, anyway - make your own decision
And don't give up
