Pls help me identify what these are

Hi, so I woke up two days ago and woke up with this on my lip. Originally thought it was a cold sore from stress because I’ve been stressed a lot lately and I tend to get cold sores from stress a lot, even as a kid. But using Abreva only made it worse and today woke up with it look like this. There are a few things I think it could be such as a chemical burn from my facewash (recently accidentally used my Panoxyl on my lips), or even a sunburn on my lips but now there’s clear pus coming out so I cleaned it and put some antibacterial ointment on it which is why it looks so shiny. It’s painful to do anything, i.e eat, talk, smile, drink. Basically anything to do with my mouth so if anyone also has tips about that, GREATLY needed. Any tips, ideas or recommendations are greatly appreciated and if it doesn’t get better by this weekend I will be going to the doctor. TIA to anyone who reads and replies!
