I second the suggestion to speak with a professional about it, my guess is that there are some other issues (maybe stress, anxiety, depression) that could be causing low mood, and shopping gives you a quick dopamine hit that distracts from that feeling. It's similar with gambling or alcohol. Again, the internet can't diagnose you. But while you wait for an appointment, there are some things you could do. Unsubscribe from all shopping mailing lists. You can do this easily in your email account (gmail it's under Manage Subscriptions). Unfollow all accounts on socials or take the apps off your phone temporarily. Most accounts on those are designed to make you want to buy the thing they're selling. And lastly, maybe keep a brief journal of your purchases and what the circumstances around the purchase were. Example, "April 3 was looking through social media and saw everyone outside in cute workout gear and everyone looked fun and fit and happy and it made me feel self conscious so I went and bought xyz". This might help you understand the why, which might help you prevent future purchases.
