I see... the type of exercise that helped me is intense exercise. If I do a mild cardio or mild exercise, meaning walking or medium or less effort on the exercise bike, I am not increasing enough serotonin to offset the upset and irritability. This has been my experience. So with that being said, unless I do hard-core/intense exercise, I do not feel the benefit from exercising. Does this make sense? Should you have any questions regarding diet or any other thing I am more than happy to help. Again, I am not cured or anything[emoji4] I am grateful if the intensity is down as I usually am drowning in the dark pit.
