What helped me was deleting my credit cards from PayPal and Amazon so that I could only use money that was actually available in my bank account. I unfollowed all the makeup accounts that I used to follow on IG, and cut my Sephora emails down to once a month. I then did a massive cull of my stash, put looked at it and said to myself well, that’s about $500 that could’ve been spend on other things. For the stuff I kept, I started following panning challenges on reddit and IG to switch the compulsion from acquiring to finishing products. I also started keeping a budget on YNAB so I know exactly what’s in my bank account at any given time. This didn’t happen overnight; it’s taken me a couple of years to do with the help of anxiety counselling and practicing mindfulness every day. You can do this, just start small and take it day by day.
