I can relate!!!! I work really hard for equilibrium.
Suggestions: GOOD multivitamin, Have your Vitamin D level checked. Recent research showed huge # of people have deficiencies, even with lots of sun and fortified milk.
Also, GOOD omega supplement, with at least a 7/1 EPA/DPA ratio, per my M.D. I use Omegabrite (Omegabrite.com). Chosen after much research on my part. It is expensive, but lasts a long time. I keep in refridge and take right after a little peanut butter per my M.D.'s suggestion.
Do some research on the web, before you take any suggestions so you know why you are doing the things you are doing.
And as already mentioned, adequate, good sleep is a must, as well as counting your blessings, exercise, and perhaps a mild antidepressant.
My thoughts and prayers are with you.
