By all means do what you need to do in serious cases. I would of course look at diet...eliminate all white sugar and flour and trans fats. Make sure you are eating sufficient fats for your body type. If you don't have the right fats, you won't have the right nervous system to handle this. Don't fear chocolate..make your own with stevia and dark chocolate if you want. It ups the amount of seratonin. Get enough sun every day. Fresh air. Daily walks..at least two short ones.
