Yeah, my t likes me to "put them in a container" until the next session. I've told her they don't stay there. Journaling helps get them out and I can go back to that in therapy to see what was going on. But then, I usually cannot get back to that place/feelings either. Feelings, for me, are not something I can just "decide" to feel at one point and then "decide" to put away for later. That concept just eludes me. So, I'll feel my feelings when triggered, maybe journal, then shove them back and resume auto-pilot (which I hate because it feels so fake and empty). Then, I'll get to therapy and be "fine" and can't recall those feelings to work on, even if they are written down. It is so frustrating. I would love an "on-call" t to be there when it is happening. (Sometimes I e-mail her in the moment, to capture it, but then later I will wonder what I was so upset about).
Hang in there, you aren't alone
