My T also asks where I feel things. That seems to tell her something usually on what kind of emotion I am feeling.

The thing were you go up and down with the emotions, after you unfreeze sounds so common in this thread.

I know my T says to ride the wave. Feeling will come and go and just allow yourself to feel whatever it feels. That was huge for me, because feeling is new to me. When I started to feel, I couldn't handle the intensity of it.

Last week I told my T that I am sad with some anxiety with it. She told me that anger is easy for me to feel, I am like this person did this to me, and they are an asshole and I won't talk to them again. But sadness feels more uncontrollable, so anxiety comes along with it, if you are not used to feeling sad.
The one thing I have found that works well with overwhelming feelings is exercise or just a walk around the block. It is amazing to me on just how well this works. Gets you breathing deeper, gets the tension out...and normally I feel better afterwards. At least I sleep better at night.
