This, exactly. If you really enjoy doing something, don't make it your job. I loved messing with computers when I was a cook. So I changed fields many years ago, and I don't even like looking at a computer when I get home.
I can see both sides of this. I could certainly see losing the joy of a hobby, if you were hands on fixing things all day, or dealing with the business side stresses of cash flow.
However, I think there are functional skills that that OP could acquire that could translate over any number of industries. For example, a good salesman can move that selling/closing expertise across industries. Or marketing, or other disciplines.
If possible, the OP should consider continuing or completing his education - that is his best defense in a vacillating job market - and try to get some training and background in skills that can translate where ever he may go. Get the skills, pay your dues, keep an eye open for opportunities in the industry and see if you can get there. It might not be immediate, you might even make a lateral move in from another industry.
Like I said, I have a squiggly career trajectory - up, down, back and forth, fortunately mostly up. And I am fortunate to be involved in a general area that I had a passion for in school, and at work, and even as a side project (call it an intellectual hobby).
It may be the case that the OP could get the skills and training in something (say for example BD/sales), start in one industry (assistant sales), move to another industry (up to sales manager), and get fat in yet another industry (sales VP). I've seen it done quite a few times, whether the individual had a community college degree or an ivy league sheepskin, if the person is hungry, smart, motivated ... and focused ... amazing things can happen.
