dealt with depression most of my adult life and my health is garbage from my genetics, mostly cholesterol and allergies. This past year got diagnosed with ulcerative colitis(basically same as chrones disease). Life is better for me without taking any depression meds. I have days where I "cant get right", simple things that I cant remember.
I create huge projects to keep my mind occupied, but having someone to listen and understand always helps. my close friends know I have lost weight and know I will not eat unless I am at home, but only a few actually know or care why that is
talk with the kid all you can, it may help more than you know
