- Can you work on your own stuf to grow as a dev? If yes, do it, you don't need a company to grow you.
- Lie on your resume and to the next potential employers, don't tell them you were only doing support.
Out of curiosity, why wouldn't you leave this job that I described?
I wouldn't leave the job, because I need it. So this tramples every excuse to just leave without an immediate alternative. Also, most jobs suck, it's possible but don't be so sure you'll be better off somewhere else. And of course if you face psych issues and in a bad market, it's even worse to be unemployed.
