See if you can find "The Creative Fire" by Estes. SHe talks a lot about the cycle of the creative artist. It always ebes and flows.
Have been doing this for over 65 years and in my mid 30's i put everything away and thought about selling it off when a friend offered to buy it and when I came to my sense sell it back .
I didn't take her offer, but I did have a period of several years where I just didn't care about working. However, since that time, the "down" time varies but I never think of selling it all and walking away.
Try to find something totally different to work on, something that makes your heart sing (certainly not models )
Just now, I had a major happiness by deciding I had nothing to lose and trying a trick. I just got a 12 inch Bausch and Lomb lens today from fleabay. When I opened the box and looked at it, my heart sank--my 136 dollars was wasted for sure. The inside surface of the rear lens doublet looked like somebody polished it with steel wool. Scratches so bad it was totally worthless. So I got out a pice of cotton and put a dab of Ultra-Brite Advanced Whitening toothpaste on it and rubbed it around a couple minutes. Then squirted some windex on a piece of toilet paper to clean off the toothpaste, and the lens was clear as a bell. Amazing. Now I can proceed to try to repair the 1912 Betax #4 shutter which doesn't work, which is why I got the thing for 136 bucks. Wish me luck.
Sounds like a passing phase, look forward to hearing how you overcome the feeling. I'd recommend you go see a Wynne Bullock show. While I know him for the black and white work, reminiscent of your "Garage Sale"...In his lifetime he did Sabbatier/Solarizations and took photographs of broken glass on slide film.
I have to print all my best from each and every film I ever shot. FB archival. I've been doing it for the past 4 years and I have about 10 years left in order to finally finish my whole collection, at the rate of a dozen 16x20 or 20x24 prints or about 25 11x14 a week.
Some masterpieces in there. But sometines I do ask myself why do I bother with all this. My answer is thay I am extremely stubborn and that I was born with a camera in my hand. Therefore I won't quit. Everybody has a vice.
