I overeat when mildly stressed and lose weight like crazy when quite stressed, especially when the stress is chronic and not soon resolved. First divorce, for example. Sounds as if you might be in the second situation.

Make sure you eat healthy food so as not to compound the problem.

My blood pressure also rises with stress. Monitor it, talk to your doctor, and exercise or do whatever reduces your stress. I'm seeing the doctor as my blood pressure is spiking. She recommended an Omron upper-arm cuff model for home testing.
