I have POTS, and have successfully decreased my exercise intolerance quite a bit over the last decade. For me, they key was starting small and increasing exercise SO much slower than I wanted to. When I started out, all I could do was about 5 mins a day on an exercise bike or rowing machine--anything I could do sitting or lying down. Eventually I built short walks back in, then gradually longer walks and bike rides. Exercising in a pool can also help, because the water pressure increases your blood pressure a bit. It's really hard to know where your limit is, because it can change so much from day to day. It's also really hard to have the discipline to do less than you think you can, so you don't wreck yourself for the next day. You won't succeed every time, but it's really worth it to get super familiar with where your limits are, so you can stay below them with some extra buffer room.
