I commend your bravery in articulating the difficulties you've been having. That's not an easy thing to do, and itself speaks favorably to the chances of your getting better.

Now having said that, it sounds to me like you're suffering from a minor case of dysphoria, which could be brought on by any number of exogenous or endogenous factors.

Making any definitive recommendation based on such limited information would be tantamount to a diagnostic Hail Mary; and the dubious prospects of success even further diminished by the fact that I'm not a doctor (though I have seen virtually every episode of House M.D.!).

With that disclaimer however, given your age (and a few other subtle signals) I'd be curious to know if you've had your hormones checked within the last few years; specifically your testosterone levels?

I'm consistently suprised by how few men in their 30's and 40's are aware of the inevitable decline in testosterone all men will contend with, the fact that their levels are probably already in decline, and more than anything else, the often significant impact low free testosterone has on mood, vitality, sex drive (of course), and body composition (among others).

Also of concern is aromatization, which is basically the degree to which your body is converting testosterone into estrogen. This is another way your general mood and enthusiasm can be seriously affected as a man.

Hormones aside, consider taking Adrafinil and/or Tianeptine. You can learn about the latter here: http://www.tianeptine.com (that site sells nothing and I have no affiliation with it) and can purchase easily online. Tianeptine is the closest thing to a cure for light to moderate dysphoria, generalized anxiety, and depression I know of. It's also neuroprotective and works immediately. I'm obviously an evangelist for it.

Wishing you the best.
