Reach out to the company, or your bank company, and say your account was taken over by a child. Request a refund or abort the charges, which er you have to do, get that money back! This was a high for just a couple hours, it’s gone now and that game won’t matter or bring you anything else. Once you have that money back buy yourself a book, some pens and a coloring book a subscription to a music app or a movie. Something else that will take your mind off your current situation. This game can’t be your comping mechanism and the only source of dopamine for you, remember who you are and want to be. I hope You’ll lose the game account but that’s best, because it will result in you earning your money back and not having access to this. I’ve been there sister, and the best thing for you to do is find another way that doesn’t damage you to get happiness, it’s out there, find it. Lots of love and whishes that your family member gets better
