i need help

Hello everyone. i'm 21/F and this year i started collecting kpop cards. it started off with just buying albums and pulling cards from there, but then i found a community on instagram called buy, swap and sell, where some accounts sell cards. it started off with me joining a group chat that was updated each time there was a new set of cards to buy. i bought just one set. that was it. 7 months later and im here. each pay check i owe hundreds to people because i claimed cards in advance. I went away this weekend and spent $500 on cards at stores in person (they were all overpriced but i was in the moment) i had to ask my parents for loans for "pavpal debt" so i could cover bills after i spent all my money on cards. I have lied about having paypal debt so i could pay off cards i claimed in advance. my parents don't understand where my money could be going. they think im just getting ripped off from paypal or afterpay. I need to pay back friends as well. Next wednesday im paying off my last claim and then deactivating my account on instagram. i want to find another hobby. getting the cards in the mail give me dopamine after a long day at work. i need to find something else to give me dopamine. im sick of feeling ashamed and disgusted about my purchases. the money could be going to so much better causes. just feels like i've wasted it all. i've sold important things just to make back money i owed people.
