Grade: 3
Exercise intolerance. Putting the starting date to be Jan 1 but was actually a gradual start. Possibly getting worse.
Iron supplements, also following up with doctors/changing doctors when they didn't want to give/interpret ferritin tests without low hemoglobin. (I might've also had some post-viral stuff at some point too--not sure.) Also made an effort to rest and gave extra attention to sleep habits and hydration.
