Welcome to the board (I just joined, too!) So sorry about everything. I started getting multiple panic attacks daily about 3.5 months ago. came out of nowhere and has been so physically and emotionally debilitating.
I do suffer from physical issues even when I'm not having a panic attack. In fact, about 7 days after the panic attacks started, I developed 24/7 dizziness/lightheadedness. Even when I feel no anxiety, I feel like I'll fall over. I also am getting more headaches, neck tension, GI issues. I think anxiety can affect the human body in incredible ways. The ER doc told me one person went completely paralyzed on one half of her body. It lasted for about 3 months, then switched back to normal. It came on because of severe anxiety (not a stroke). He said anxiety can sometimes make our bodies really go haywire in unusual ways. I know it's easy to think there's something else wrong (I was convinced I had MS or some other horrible disease), but for most people it's anxiety rearing it's ugly head.
I do have some slight positive info for you. My dizziness was so bad, 10/10 each day, for months. Although I still suffer from daily panic attacks, I've really been trying to do breathing exercises, therapy, exercise, and I even bought a ukelele. I figured I could active a different part of my brain and teach myself to play, so it couldn't focus on anxiety. Long story short, just in the last few days my dizziness has started to decrease. It went from a 10/10 to a 3 to a 5 out of 10. Will this last? I don't know. But I'm trying to see tiny positives and think as I slowly chip away at anxiety it will help resolve other issues.
It's easy to feel isolated with this disorder, and I often feel that way. I also tend to have catastrophic thoughts, like "I'll never get better!" I sincerely hope you (and all of us) find some relief. I think it's a slow process that could stall out at times. I'm glad to be here where we can lean on each other for support. :) Really hope you get better! Maybe try taking up a hobby at home that can redirect your brain's energy….?
