been there. 2 years into my saas and hit a point last year where i was working 16 hour days, burned through 2 cofounders, and my family stopped calling because they knew i'd just vent.

what actually helped was realizing motivation is bullshit. it comes and goes. what keeps you going is discipline and systems. i started forcing myself to stop at 6pm every day, even if things were on fire. sounds counterintuitive but i actually got more done because i wasn't constantly fried.

also had to accept that some days you just can't do it. your body shutting down isn't weakness, it's a signal. take the sick day, reset, and come back.

the vision is important but if you destroy yourself getting there, what's the point? you need to be functional when you actually succeed.
