So I'm in post covid right now and just started getting back to my normal (still kinda figuring that out) and recently started going back to the gym because it's way past due the pandemic damn near killed me and I wasn't in the best physical health to begin with. 28M 5'9 weighing 310 pre-pandemic I ballooned back up to 370 because stay indoors and don't get near people (which as an introvert I had zero trouble doing). Anyways recently the gym has been really kicking me lately even though I'm only doing a mild pace walk at 2 mph for 30 minutes then I proceed to the spa area and either do a couple laps or tread followed up with steam room and hot tub to end everything on a relaxing note. The second I get home, and this is where my question comes in, I feel incredibly exhausted like 24 hour minimum wage job non-stop. So I bring this up with my doctor and they kinda shrug it off and I find myself breaking it down and agreeing because with BPD and all of its symptoms, how do you differentiate post-covid with mental illness?  At this point my plan is to just keep a record of things and if they don't improve say something to my psychiatrist when I see them in late August. What do you guys think? Has anybody else had something like this happen to them?
