Not sure if OP is a male or not but if you are get your testosterone levels checked and if they are low, fix them. I was going through the same thing at the same age. Your milage my vary but that was a complete game changer for all aspects of my life.

I would also suggest getting tested for vitamin B12 levels. I began taking B12 injections to compensate for a very low level and it has been a night and day improvement in my energy levels and ability to focus.
