Grumpy,
If you're not happy you're not happy. The life style is certainly difficult to adjust to, especially if you commute. Seniority and living at your domicile certainly helps. I commuted for 18 years before moving to my domicile. IMHO I would get a taste of seniority or perhaps switching to another employer before going back to helicopters. I will tell you that my first year a UAL working for $28 per hour as an engineer made me question what I was doing.
Since you asked... Look at USAJOBs, offshore to oil rigs (PHI etc.), state agencies such as Arizona Highway Patrol, Boarder Patrol, or power companies like Salt River Project. The air ambulance jobs are very rewarding but can be transient based on profitability (or an accident). You can also look into a Army contract instructing gig at Ft Rucker. There are really cool helicopters jobs out there but most of them only pay peanuts. If it were me I would lean towards a Federal/State job.
Good luck!
