[Copypasta] Among Us concerned father

Hello everyone, concerned father here. Recently my 7 year old son discovered the video game “Among Us” after playing it on his computer. While i didn’t mind at first, it soon began to affect his character. Within a week, he had been screaming 'sus’ in his sleep. When asked to do his homework, he called me a stupid father and said ‘kicked’. His grades have been dropping heavily since that day and whenever i refuse to give him my credit card for cosmetics he threatens me saying he’ll “eject” me. Yesterday I entered his room to witness him listening to extremely loud rave 'Among Drip’, he put a bunch of pillows in his shirt to make himself look big and now calls himself a “crewmate”. He refuses to go to bible study unless we use “vent” to get there. I don’t know what that is but he refuses to take any form of transportation except that. Please I am so concerned, what do I do?
