What Kari said, plus 2 words: Don’t look! ( stores, websites). Which for me stimulates buying.
You may enjoy some of the blogs on year without buying- clothes, sometimes other things.
I like Kari ‘s point that you can still discard ( or put things in a holding zone) because then it can be not just not- buying, but more style- honing and discernment, needs- assessments in areas you may not thought of but would like later.
Also what Lisa said- make positive changes to do other things that make you happy.
