I know a few people who aren't able to email their therapist's but they write out their thoughts and feelings and actually snail mail them to their therapist's. You don't have the "immediate" gradification of a response, but in most cases, the therapist is able to pull the letter out at the next appointment and he/she is able the critical issues. I know that isn't the same as the immediate response of email, but it's better than not having any way to communicate! I hope you're able to find the right compromise!
