I feel you. Seriously. You've clearly considered many, many options, but I've had analogous decisions to make in my own life and there are times when an unusual and radically different approach works well. A lot of times those huge differences arise because of external circumstances, sometimes we're forced to endure them, other times a decision you make has profoundly unexpected consequences. And sometimes you have to make a conscious choice to make a severe change yourself. Perhaps it's time to make a radical, conscious change in your work. An anecdote. A close friend of mine divorced which ended up being the best thing for him. Weirdly, not long after, one of my private students broke down in class. She'd been battling for some time to save her marriage. I explained about my friend's situation but she was vehemently opposed to divorce. A few months later, she and her husband were working towards reconciling. Actually seriously considering divorce somehow spurred her into finding a way to compromise. I've left out all the details but it was thinking the unthinkable that seemed to be the catalyst she needed. Something radical, Sorry I can't offer anything concrete, only vague unactionable suggestions that are probably unfeasible.
I might have an in on a job though. I was discussing this all with a friend and it turns out their brother works at one of the garden centers I got turned down for the other year (small world of hours, huh?) so he's gonna ask him if there's anything that can be done. Put a good word in for me. It would be awesome if that was the case, cause it's literally my favorite garden center, if only because they have tons of artisan pots and lawn ornaments and to be surrounded not only by plants and weather, but hand made art? Dude.Perhaps it's time to make a radical, conscious change in your work.
