Stress makes me lose my appetite. It has all my life. The 2 times I struggled with massive anorexia weight loss I never felt hungary. It took years after I recovered both times to ever feel hungry again.
My life has now settled down into my own environment. Stressful things still effect my appetite but living alone I am better able to control & will find something to eat that does taste good to me that is also healthy.
I never eat normal even when at a healthy weight. I do well if I eat one meal a day though it is always a healthy one it seems all my body needs to keep going with all I am involved in & with all the work I do around my farm
