If it's just the mid life" Why do I even bother some days/why do I exist" then I'd say it's normal. Not pleasant, but a normal part of life to feel down at times.
I appreciate this Scott, you've described my feelings pretty accurately. I do admit that I am probably battling with a little depression and it needs to be addressed.
