Dude. At best case scenario you'd end up like that:
Just pick up a hobby; learn to play guitar, start going to opera or become a game streamer who's in it for the fun not the fame. Or, if you really want to go that way go to Czech republic, enjoy the food and the medieval scenery, may be cosplay as a black Bohemian knight for the lulz - then go to the Polish-Ukrainian border and volunteer to help Ukrainian refugees somehow. This way you'd bring more benefit to everyone, then just jumping into a meatgrinder.
