Anyway, I discovered over time that much of my anxiety and panic attacks is centered around feelings of control

Definitely this is what probably triggers the majority of what makes me anxious. I don't like not having control, of myself when I can leave a room, my body when I put medicine in it or anything else. You are definitely on point in what I go through. I have been in therapy and tried so many times to relinquish control, but it is only when im on Xanax is when I can do that, which is why it works very well for me. When im in that state I accept everything that is going to happen to me.
