Ask HN: How do I resign?

Without giving too much detail, I'm a pivotal member of my small startup.

Things are to a point that I am unable to cope with the effects it's had on the rest of my life nor can I even manage the workload of the rest of my life weren't an issue.

Part of this is my own failings. I got into the role much too early in my career and have a number of shortcomings that definitely didn't help me along.

I tried hiring but struggled to find someone good enough at the salary I was permitted to give.

Overall, it's coming to an end, and shouting out "I quit!" becomes more attractive by the day. Even by the minute.

All that said, I want to be responsible while still moving quickly toward my goal of being gone. What things do I need to consider? Am I open to any legal ramifications (co-founder status, technically a C-level)? I'm in over my head and can't sustain it any longer.
