A very depressing morning because of an uninvited guest that suddenly appeared under my chin

I looked in the mirror this morning to wash my face and was really surprised to see a bulge of blemishes under my chin.
I guess it was because I went to bed last night without cleansing properly since I was tired; it got really bad overnight.
It feels hot to the touch, and it hurts so much that even a slight brush makes me tear up, so I can't even touch it.
Even when washing my face, I broke a sweat trying to create as much lather as possible and wipe it off very carefully to avoid friction.
Even after going to work, I was bothered by the way it kept rubbing against my mask, so I ended up stopping by a pharmacy during lunchtime to buy acne patches.
It is so big that it doesn't even fit well with a patch, but I barely managed to apply only sunscreen because I was worried that covering it with makeup would make the inflammation worse.
I have been under a lot of stress lately, so my sleep patterns have been a mess, and I can feel my skin immunity hitting rock bottom with my whole body.
Today, as soon as I get off work, I plan to gently remove my makeup first and then apply a generous amount of tea tree ampoule with anti-inflammatory effects to make a face mask.
I usually get compliments on my skin, so it makes me really upset and depressed every time it breaks out like this.
I just hope this hard and painful unwelcome guest subsides quickly so I can regain my peaceful and smooth jawline.
