Yes. I used to fall asleep after I would come out of an anxiety attack. It's pretty intense stuff for the body to go through. When possible, just give yourself some time to relax and regroup. Try to get some extra sleep and make sure you're taking care of your body (eating healthy, not skipping meals, avoiding alcohol and cigarettes, etc.) as best you can.
This is VERY common and happens to me when I get anxious sometimes.
You really just have to wait it out and learn to adapt to it if it occurs often.
Hi I can relate to you feeling slow and not with it. Everytime I go in a supermarket or place with florescent lighting I experiance a feeling of low cognitive ability like I've forgotten how to process things around me its very annoying and quite disorientating . I suffer with anxiety and panic it seems to make me have real bad co ordination and blurred vision combine that with a vague feeling and it seems difficult to function .I just try to get on with it then it .. hope you sort it out regards Ross.
