Email causes so many problems in therapy! My t and I struggled with it a lot. I suggest asking specifically what his rules are and what you can expect regarding replies. Same with texting. If what he allows isn't going to help you, then perhaps you do need a new t.

My t asks me a lot of questions. Can you discuss your concerns with him? Can you tell him how you feel, like you posted? He should be more understanding, in my opinion. If you aren't getting the help you need, then it's time to find someone who CAN be more effective. I'm sorry you're feeling bad. Hugs!
