I agree with core-questions, it is burn out. When I had it, similiar symptoms, I took 4 months vacation to go bike riding. After which I was fine again.
I hope you can find a way to relax and re-energize. You said you took a vacation, how long? I find for it to really help it needs to be a MINIMUM of 3 weeks. 1 week to ramp down, one week to actually relax, last week for me is always ramping up again.
