I have ME/CFS, which is an incurable chronic illness characterized by Post Exertional Malaise or PEM. In short, ANY sort of exertion (physical, mental, emotional) causes a backlash of flu like symptoms and can permanently lower your functional baseline. Doctors don't currently understand why it happens or how it works, but it seems to effect the mitochondria and energy production in the entire body.
I have a decently bad case of ME/CFS, I cant work at all and I can barely leave my house. Even positive, non triggering socializing causes an upswing in symptoms for multiple days afterwards.
And it just feels like my abusive mother has moved into my body. I feel like this illness acts
