I definitely think there is and have struggled with it myself. I’m also very prone to overtraining (regression in workouts, inability to sleep, loss of strength, increased water retention, poor recovery, etc) easily in 4 weeks or less if I’m training hard.
I'm in the same boat, bro, I do not know if it's stress, excess cortisol, supra renal fatigue, I do not care what you call it, just you're fucked, you can not sleep well and you have to keep pushing hard, you follow keep pushing, but do not feels healthy.
Has taken a lot to help improve it. Think the variables can be different for everyone though which is an issue because the medical field wants to see consistent symptoms, test results, etc in order to diagnose and tend to say things they can’t diagnose don’t exist (another that comes to mind is HPPD).
