Refractory AChR+ gMG Flares: How Long Can They Last?

Have had a very bad flare since exactly April 1, 2025 (no joke) and it still shows no sign of going away as of May 19. Haven't felt this bad for years. Never had a flare that lasted this long. Any wisdom out there on when bad flares die down? This is pretty much into the intolerable category: breathing is very difficult, feel like I weigh 500 lbs (actually 170). Substantial brainfog and visual difficulties.
