I've been in other situations where I've burned out, and am still recovering years later, kind of lost and disenchanted with tech in general. However, you sound mostly like your work is under-appreciated, so maybe you're not getting whatever reward you might have been hoping for, and that you're sacrificing yourself for no purpose. In my opinion, if you sacrifice yourself for some other goal, it better be tangible and worthwhile to you or someone else personally. A company is a company, and mostly that's not worth sacrificing yourself for. My recommendation is one of two things. 1) Take a sabbatical. Explain the situation to the founders, and go fuck off to wherever you want for 3-6 months. It would be unpaid, but you'd have something to return to and re-evaluate. If they don't seem accommodating, then fuck them, quit and work in a bar. 2) Quit and go work in a bar or go back to school. It only takes one burnout to realize most stuff isn't really that interesting anyway. Find some people to hang with and re-evaluate your social life if it sucks.
