Do you mean to say you're giving up on dev due to failures to land a new dev job...or you are trying to transition out of dev and not able to find a job in a new industry?
I guess either way, an anecdote from own personal experience, I was looking at other options myself...I was burnt out on dev, looking to do something related but I thought might take a burden off my shoulders (QA/support), that didn't work out...but long story short, I just decided to embrace who I was--I'm a dev, and I'd like to think a good one, not to say a bigger transition is out of the question, but I found that it was more realistic to adjust my "internal" dials rather than escape to an entirely new career. That may or may not describe you, but I guess I would say to bear in mind the solution isn't always an external change of circumstances.
