Lips🙄

My lips are cracked in the corner and under neath them looks like it’s little cuts and gets crusty and I don’t know what it is. I put on so much chapstick but it doesn’t help anything. It hasn’t spread to anyone else even when I share drinks and whatever. Does anyone know what it could be or how to help it? It’s so embarrassing and I just want it gone. I’m not going to the doctors until next week but I want it gone now. Please help!
