(((hugs))) Yes it does seem like a bit too much of exposure therapy for you. I hope you express this very clearly to your T. Perhaps then your T will help you take baby steps first... like just talking about it, or thinking about it briefly, to visualizing an empty gym etc... Sometimes when we go too far too fast we all but retraumatize ourselves, and that does no good.

Everything can be ok. You are ok, and brave to have done this and done it so well by yourself. Now breathe. You're safe.
