Hey guys so been in bit of a prickle in the last 3 months, I was tapering off an antidepressant called amitriptyline and early Feb, my nervous system blew up. Been having bad anxiety since, and noticed a couple of odd things, for example anything stimulating makes me get symptoms which are very uncomfortable: instead of getting a calm, relaxed energy after exercising or having a warm shower, I just feel over-stimulated, can't focus, light headed etc... Basically like my nervous system is over stimulated and can't calm itself, like it has no brakes.

&amp;#x200B;

Had blood pressure checked at GP - no problem. My resting heart rate on some days is pretty high.

&amp;#x200B;

Other symptoms include restlessness, discomfort even when sitting down chilling at home etc.., tingling sensation in my legs. 

&amp;#x200B;

Has anyone ever had this before? I'm particularly surprised about the symptoms after exercising as normally in the past  this was my go to method to tame symptoms. Since I know cardio is great for my CNS, I'm not going to stop doing it, but just means that the one thing I normally look forward to when I have bouts of anxiety is very uncomfortable for a few hours after.
