I struggle with feeling unimportant with my wife and occasionally other people when I am disappointed in her response to me (e.g. she is busy working when I want to talk). I also have this reaction to my T when she doesn't respond as I would like her to. I don't email with her, but I can relate to it in the times when she gives me a brief or sometimes no reaction to something I've talked about, when I was looking for something deeper.

So I think your feelings are larger than the unresponded to email, as you recognize in your "over reaction", as you label it. The way I want to be is someone who is secure in my belief that I am important to my wife. Fifteen years of love and support and kids can't be undermined by one evening where she's too busy for me. I would like to feel confident and say to myself, hey, tonight she has something that she needs to do, but I understand it has nothing to do with me or how she feels about me. Sometimes I get there, sometimes I don't.

With T, I'd like to also feel secure that she cares about me and wants to help. Her inability to always get it right, to say what I need or want her to say, isn't about her lack of caring for me. This has helped me articulate to her what I need, such as "I was looking for you to give me some more feedback about this" and the like.

If I were in your shoes, I would send her another quick email and say something like "it would really help me if you could give me a really quick response that you got the email and you realize this is an important issue for us to discuss further."

Asking for what you need directly might feel better than quitting therapy. Just sayin'.
