Hi there! I can honestly say I often feel like that, for me, it happens most frequently after a panic attack. In fact, I am feeling like that today, and I didn't recently have a panic attack. So, I can say yes, I know that feeling!
Dealing with panic and anxiety for 8 years off and on...right now more on than off. Major health anxiety as well!
New found issues with agoraphobia...working on that too.
I am NOT weak, I am just down right now. I am doing what it takes to get my life back!!!
Best Wishes to all...Tammy
