You might be experiencing a mid-life crisis (assuming you are not undergoing depression). Fortunately, I found what I was experiencing by just openly talking about my feelings to my friends (and not spouse/girlfriend).

For me something snapped one day after age 35. I was relatively successful, married and I suddenly lost interest in my work or any kind of work. Even retired for 6-9 months, only to come out extremely bored - pledging that I would never ever take a retirement. It took me 3 more years to understand what was happening - I felt that at 38 too, and ideally it was still too early to experience a mid life crisis.

Some tips based on my experience:

1. Take very good care of your health. Regularly exercise (including at least some resistance training) and mostly healthy food. Measure health parameters. 2. Rule out any medical illness and/or deficiencies. Get a full body checkup done (including a detailed blood/urine tests). Do not cut corners here, but if not recommended, you could skip tests involving radiation. 3. For a month or two - take less stress (don't overperform or even try to overperform) and find periods of emptiness. After some time fill in those times with some activity that you love to do - doesn't matter how illogical it sounds. Let your intuition guide you. Make notes weekly. 4. On the work side, try to get into a management role. My situation was a little different, I was not an employee.

I do not know whether I am out of the woods(at early 40s), or just got used to the new reality. But I do feel quite better and may have made significant progress - only time will tell.
