Don't over think it or start self doubting. Are you getting interviews? As previously asked - where are you located?

1. You must network. Make the effort to go to local meetups, etc. One problem you have is that you don't have other developers around. Knowing how to market yourself comes with awareness and experience you get by having relationships with other developers. Get out to a local meetup or something.

Without knowing more, in general: 1. If you're able to reduce your salary requirements then look for something that offers you a chance to build skills (sacrifice compensation for now). 2. You may need to relocate for greener fields.

As for tech choices, I think it's more about being with a team (or project) that is actively practicing high-quality code craftsmanship. Languages come and go, but delivering high quality code is a skill that sticks.
