We as developers have privilege to work remotely. Don't excuse yourself saying "I need an office and people around". That's just not true, as you gain so huge amount of perks when you find a remote job it's madness if you don't even try it for a year or two.

If you really go crazy alone you can always find coworking space almost anywhere in the world.

Moreover, constantly look for opportunities. I recently heard very wise words that the best time to change your job is when you are perfectly happy with current one.
