You're still young. Try to get yourself somewhere closer to a tech job than construction. I had a lot of quiet times working as a hardware technician in past and other IT (sys-admin) jobs, while working on software projects and learning more about software in my spare time.

Of course, it is not so suitable if you are traveling a lot, but the general advice here is not to work so far away from a tech position, when you're quite passionate about software & tech. Communication and interviewing skills are something you can learn, don't let that hold you back from actual interviews, keep interviewing for jobs that you want; you'll get better at it.
