What is this 😭🙏

Okay so this started out as what I thought was a pimple, I get them quite often as I have body acne so I wasn’t too worried and I put a pimple patch on it, but the pimple patch did not make it any better (and normally it does) well it popped and now there’s a literal hole in my boob, and idk what it is, I cleaned it and put some triple antibiotic on it, but it got worse. Does anyone know if I should be worried about it???
