How to stop paranoid spiraling

i had some troubles with an old banking app that gave me a cash advance, they really prey on vulnerable poor people. i gave them my new bank info to pay them but couldn’t even do that in their app, then they wouldn’t let me delete my bank info and they had my transactions and credit score and stuff. i managed to get it disconnected and deleted my bank account from it but now i’m terrified that they’re going to take all of my money. that i’ll wake up and all my money will be missing. i’ve been having a lot of money anxiety because of christmas. but now this just makes it way worse. so on top of that i’ve started feeling like i am being monitored and someone will steal all my money and like people are watching me in my house like all eyes are on me. i took my propranolol but still feel really anxious. how do i get rid of the thoughts??
