A lot of people here are suggesting dealing with the burnout/fatigue/frustration first. That seems like good advice.

Sounds like you can/are supporting yourself with a half time job leaving you lots of other time. That in itself is an awesome asset, really awesome. Use it. Take some time at a lower work rate. Put that energy into something unrelated for 6-10 weeks.

One option is to spend more time socializing, with family and relaxing. Another is to pour time into something unrelated. Learn a sport, instrument, theatre, etc. Get a little obsessed if you're that kind of person. When/if you get back to putting your mind on startups again, it will be a new round, like boxing.
