Only you know what's right for you. If I were in your position, though, I'd absolutely leave. There is a wide world of well-paying, very interesting, dev jobs out there that are also at great places to work.
Suffering in order to maximize income is, for me, a bad deal. You can enjoy life and make very good money even if it's not technically the most money you can possibly make.
