Anxiety and Depression are two of the most common symtoms (or effects if you will) of any illness.
Chemical changes, life changes and all over change throws most people off which in turn causes anxiety and depression.
Anxiety was one of the worst effect for me. Slowly I crawled out of it and got back to somewhat normal. It took a lot of work (no meds for me) and I was able to see the light at the end of the tunnel.
The best way to relieve it is with a CLEAN great diet, as much detoxing as you can and I cannot stress this enough, EXERCISE! Even when you feel you can't do it, you can do anything small just to move.
Stay positive, it does get better
