I would highly recommended finding other sources of joy. Buying things has been proven again and again to just give small bursts of happiness that quickly fade, this is the cycle these corporations often feed on.

Look into cheap hobbies you can do. Recovering from getting used to these small hits of joy isn’t always easy, but it will give you back more control of your life. I’m not perfect at this myself but I am much more aware of it and able to say no in the majority of my life.

You could also look into Minimalisim, there are some interesting ideas in there to be adopted, even if you don’t eat the whole pie.
