Adrenal Fatigue---I Had An Adrenalectomy---just One Adrenal---many Years Ago---I Guess

Adrenal fatigue---I had an adrenalectomy---just one adrenal---many years ago---I guess in about 1985. I made a full recovery and have lived an energetic and busy life all these years since. I am now an 80 year old woman and just lately have been having the 'fadeouts' I remember having for some time after that surgery (which stopped without treatment then). I recently stopped taking anti-depressants (with my doctor's agreement) in mid summer this year. The fadeout experience is just suddenly losing energy, getting weepy, and cold. Could this be related to my past medical experience?
