I don't know how else to explain this feeling other than guilt. When I leave my therapist's office I get a feeling of dread, like a pit in my stomach that turns into this "guilt" feeling. I have to let myself process the session - which can sometimes take the rest of the day - until it goes away. 

By process, I basically replay the session over and over again and go through it making sure I didn't say things wrong, overshared about things, missed something important that I should have said, or going over the things she suggests.

 Is this a normal feeling? Should I bring this up in therapy? I don't want her to feel like I'm uncomfortable or make her uncomfortable either.
