Sounds like you're burnt out and need a change. I wouldn't worry about the equity so much, as you've said, it has near 0 value.

You didn't state where you were incorporated, what your costs of incorporating, etc. were.

I've kept a Delaware C corp going for a few years because the cost of shutting down and starting again is more than the cost of the taxes, and I can use the structure for another business in the future. I guess it also depends on how complicated the corp structure you put together are.

Aside from the cost of maintaining the corp, if you're comfortable with keeping it, why dissolve?
