I'm sorry things have been tough for you lately. Hopefully you will find the right solution for you! Whether or not you decide to go back on the anti-depressants, I really really hope you will keep up with the Primal eating! It can only do you good. Personally, I have found that I keep setting myself up for failure by expecting perfection, but every time I mess up, it's easier to stay with it when I start eating right again, and it's getting to be longer and longer in between slip-ups.
But whatever is going on in your life, giving your body the proper fuel will help you handle it better.
YOU CAN DO IT!
