I'm sorry you're struggling. I'm not sure how long you've been seeing this T, but one thing that seems quite important is to bring all of this up to your T - and ask for what you need.

You mentioned that therapy isn't working, yet you want to increase your sessions. It might be worthwhile to figure out what you want out of those sessions, so you and T can come up with a plan of action.

As far as ideas to lessen anxiety, my T encourages me to set a space for those feelings - allow myself to feel and work towards being curious about those feelings. That curiosity can lead to understanding what my body is trying to tell me, and then journaling it. If it gets too intense or lasts too long, he encourages me to find a physical outlet for that energy build-up - typically some form of exercise, etc.
