when people in your life pretend to be experts on me/cfs

seriously, i don't invent this : my mom spoke to some doctor, a head of me/cfs treatment in a private clinic, and since then she's sure she completely understands everything about this condition. Unwilling to get corrected, or to accept it that maybe there are few wrong interpretations here and there. In the very same conversation she bragged about her new expertise, she advised me to go to the lake for a swim. Yup, you heard it right. And after all of her talking, which was very stimulating, I don't think i'll be able to walk, handle a lot of sunlight, or do anything interesting outside for a long time.
