Hi SC78,
Sorry to hear of your anxiety and stress. Reading your post, I was struck by how much I could understand your emotions of anger, frustration, despair, resentment, etc. I've been there (and probably most people in this group have as well). I've always valued "being in control" of myself and my emotions. Suddenly, with panic, it felt like I had no control. I could only respond and suffer. My world got smaller...I lost self-esteem, I avoided people, situations. It felt like I couldn't handle even a simple task.
I also used to have your symptoms of being light-headed, dizzy, etc. They still come on when I'm really stressed or anxious for a long period of time. Learning how to deep breathe, visualize, and do the muscle relation has really helped.
The other thing that I'm really trying to work on is my own expectations. I realize life isn't perfect. I realize I'm not perfect. Yet I still try and act like it should be. So much of my anxiety comes from my high expectations. No one lives without anxiety. Learning how to control it (so it doesn't control me) is what I try and keep as my expectation know.
Anyway, welcome here. I'm working through the program too...so far I'm enjoying it!
