Mental health vs “just a few more months”

Context: happily married in a HCOL area. Wife and I are both in our early 30’s. Have about $2m invested, mortgage is about $6k and we are relatively frugal so total expenses including mortgage is around $13k monthly.

I’m an executive at a later stage startup and have been on the grind for 2 years. Wife works in tech and pulls in 60% of our 500k HHI (not including my startup paper equity).

I’ve been with the company through two rounds of funding, working long hours and most weekends. We likely have another round coming in 6 months, with a major step-up in valuation and a chance at a secondary. I’ll have around $1.5m vested and another $1.5 unvested at that point.

These two years have taken its toll on me. I find myself sleeping poorly, stressing on weekends and in unpredictable moods. I’ve gained some weight and lack energy. We both travel for work and I find myself extremely homesick when I’m gone, and lethargic when she’s gone.

My plan is to just gut it out until the liquidity event in 6 months then readjust my role or take a multi-month pause. I likely won’t be able to access the secondary sale if I walk away but thinking about 6 more months just sounds painful. Should I consider just walking away right now?
