Hi EM, I can relate to some of what you've written re aches and pains, lacking oomph and fatigue, depression in my case causes those symptoms to the point where I question is something physically wrong or is it the depression (my depression is great at mimicing (spelling) physical symptoms). In my case one clue that it is depression is when I get involved in doing something the symptoms vanish only to return when I sit and try and relax.

I'm no nutritionist but it doesn't look like you're eating enough which could be causing a lack of oomph and aches and pains.

Have you seen your doctor?
