I asked for a raise this summer and they wouldn't accommodate that so I quit. I was burnt out and the company was asking for ridiculous things like 24-hour incident response without being on-call and paid for it.
Right now I am mostly playing gigs and running sound. A lot of pushing boxes and a little "figure out why the mic isn't sounding right". It's cold in Colorado, but boondocking in my truck at these remote gigs is kind of a fun challenge for now and knowing how has opened up a lot of possibilities for other fun sounding travel.
Most of my time is off, and I am spending that time writing and making music with the folks I like, and doing little experiments with analog electronics just to try and learn a bit.
On one hand, the only reason I feel okay just working intermittently like this is that a) my kiddos are grown and I don't want more b) I have enough in the bank that I can jut bum around doing these gigs indefinitely and c) my living situation is simple and doesn't have a lot of costs. I'm 45, my kids are graduating college this year, I'm not married, etc. "Freedom is just another word for nothing left to lose" and all that.
I've also have had a couple careers, as a teacher at a university and as a programmer for the web.
One of the realizations I've had is that my agency job didn't pay an amazing amount more than, say, bar tending at a good bar.
My day rate as a stage hand / sound guy is quite a bit more than my "day rate" as a programmer, but I couldn't block out any of the 5 days a week I was working to just go and do whatever I felt like. The trade off is that I don't get anywhere near as many days of work.
All that is to give some context to a point: a lot of the folks I know let their fantasy of who they are override the material reality of what they are actually doing with their time.
In that my "professional" careers as a programmer or educator, I was getting a lot out of identifying as a programmer or teacher. There is some value to that.
What I did not realize was that these identities weren't really worth much. Being a good father and respected musician (neither of which are worth any money) are both worth more to me.
Or, to put it a different way, I really wasn't getting paid as much as I was thinking I was, especially compared to other, similarly competent folks in the service industry and trades.
Giving up a bunch of freedom so I could worry about problems with my software 24/7 was neither fair to myself nor even all that necessary.
I can't comment on your specific situation, but I can say that "switching careers" really hasn't been all that much of a problem once I realized that most of what I was getting were idealized notions of "stability" and a rather class-inflected notion of my position in the labor pool, neither of which is ultimately worth very much at all.
