It's a difficult sensation to explain.   When I'm physically the most relaxed and mentally my body gets all tingly.  Almost like lightning.   I get a tingling sensation in my feet it in my fingers like the anxiety is trying to come back.  It's very uncomfortable.   I find my anxiety often causes my heart rate to Spike and stay elevated.  What when I'm like this my heart rate is lower than usual.   It's like I'm so used to being anxious and worried all the time not being anxious feels uncomfortable.

I'm not on any medication.   I don't self medicate.   Usually when I feel anxious I exercise.   I find it hard to find someone who can relate to the sensation.   As it makes doing work very difficult I don't want to sit in one place I want to go and run or walk.   Even though I'm extremely physically active walking over 10000 steps a day.
