Feeling awful

I feel like my POTS has been really bad lately. I feel even more weak than usual. Folding laundry while sitting down is really difficult. Curling my hair is difficult. Standing, even for short periods of time has become increasing difficult. It feels like my body is so heavy and that I dont have enough strength to hold myself up. I am assuming its due to getting off medication. I was on Wellbutrin for depression and while it basically saved my life, they think it contributed to my POTS so they want to get me off of it to see if my POTS will go away

But I just feel so awful. I was on 300mg then 150mg and that did absolutely nothing. Now im on 75mg and I still haven't noticed much a difference in HR but physically im worse. I just feel so physically horrible. I dont know what to do but to just vent and hope it passes.
