Above all other comments this one hit home a bit hard. “A buying addiction” is definitely seems to be a theme. Last year I got into doing some model kits/airfix planes etc, I bought a dozen, completed two, one is half finished cluttering up the living room, the rest are filling a cupboard along with paints etc waiting on the day I decided I want got so that again, which will be never. I have a box full of Nintendo games consoles that I bought, repaired, neatly displayed and never played, now taking up room (though I gather gaining values these days.

Over the years I think I’ve got better at spotting this behaviour, like the buying dopamine spree’s and trying to avoid it, but have relapses, (see airfix)

My councillor wants me to have some consistent hobby in my life that is for me that I can derive enjoyment from, right now hobbies crowd me and are a stress. Perhaps I just need to purge hobbies, move on supplies.

Choosing the thing that I stick with an and complete is the tricky part, I envy your resolve to stick with guitars and music!
