She is a new therapist to me, I hate to start the whole process over again but maybe I should.
That's a very good point.Of the two, autism is the more fundamental and impacts how you communicate. A counselor needs to first know how to talk to you, if their success relies on talking to you...
If her specialty is PTSD, but she only speaks in a non-English language that you do not know, she will be ineffective. If she understands the autie frame of mind, she can talk to you in such a way as to be heard. (That is why you should start with an ASD specialist.)
