I’ve been noticing the last two weeks my energy levels have been really low. I run frequently at the gym and all a suddenly I can’t do half what I normally do without feeling like my lungs are on fire and wanting to throw up. I’m forced to quit due to sheer exhaustion. This is highly unusual for me. Overall I’m much more tired and fatigued during the day, even though I get more than enough sleep. I feel really weak, like I’m sick or something (but I’m not). I’ve been trying to ignore this for a while now, hoping it’ll just go away on its own, but I can tell something is definitely wrong. Could this be TMS?
