Look at state, county, and municipal government. These are all soul-killers but generally come with livable pay and good benefits, and if you have any relevant skills at all, it's relatively easy to find an opening. There is also contract work for these entities, which can give you a chance to meet people, check out the landscape, and note which skills are in highest demand while you find a way to wiggle into the system.

Stay only as long as you need to or the environment will destroy you. Usually I'd say one year max, but you sound like you need more. Use your time to plan your future in detail.

Look and act happy. Defer to "authority" (i.e., the hopeless incompetent mutants who hire and fire). Smile a whole lot. Pretend that you like everyone even if you hate them all. Engage in friendly chitchat and help out with birthdays and potlucks when they come around. Fake it.

If people like you they'll give you a pass on everything as long as you don't set the place on fire or molest their children. If people don't like you then you're out of luck no matter how excellent you are, because it's government work, and government doesn't go broke, and if something doesn't get done today, or doesn't get done right, there is always tomorrow. And people just want to get through the day and go home and forget about it.
