That's what therapy is all about, being aware and able to express the feelings.

I suggest that you try to pin point the main over-riding feeling that you have. For years I had nothing but anxiety and fear that would mask all other feelings. Then your T can work with you on where that feeling comes from and how it affects you now and what you can do about it.

I don't think that you will be able to just let out all your feelings in one go and I don't think your T will expect that either. You have already mentioned that you were never allowed to have feelings or to say how you feel so there is something to start with.
