Well I haven't "been there" but for reasons that I won't get into I didn't pair anything and I closed my collection for a year a few seasons ago. What I discovered during that year was that when I wasn't worried about pairings, getting females up to weight, eggs in the incubator, imperfect pippers, advertising, dealing with customers, etc. I was a lot less stressed and thus more free to enjoy the animals I had.
In addition to the 200+ snakes you have other species to deal with, plus (I'm assuming) a day job. That is a lot of responsibility for just one person.
My advice is to scale way back to where keeping (not breeding) becomes fun again.
For the breeding programs, figure out the top two or three projects you want to focus on across all of the species you have, keep a dozen of the critters that will best advance it, and sell everything else.
Pets are trickier with the emotional investment, especially with all of the flippers out there. If you can send them to a good local home with a first right of refusal contract, that may help you deal with the rehoming.
Equipment can be sold or set aside in case something breaks, it's nice to have a backup readily available.
