Are you running away because you fear the dependency and don’t want to need her so much? She is suddenly reminding you of an abusive former therapist?
You need to talk openly and honestly with her. This is a relationship, one that has meaning to you.
1. I’m feeling some dependency on you which is very uncomfortable to me. I don’t know what to do with my feelings. Can we talk about it? (Is this transference, a healthy, good thing).
2. Remember when I told you about x, my former abusive therapist? Lately, you remind me of her, especially when you do x. I know you are not abusive (presuming) and I wonder why I feel this way? (Possible transference and great way to work through this.)
ETA. Telehealth is not ideal for many, especially with autism. Please tell her how you feel.
