Sleep regression losing my mind

I am losing my mind. My baby is almost 10 months old. Always was great at self soothing until 8.5 months old. Been teething terrible and backtracked on sleep. Waking every hour without Tylenol. Only sleep half hr for naps. Fighting going down for naps. Yes I watch wake windows and get him down at the first signs of tired. Sometimes he goes down ok but most of the time he is squirming and crying and fighting his sleep. If I put him in his bed like I used to he SCREAMS and screams. I end up getting him because it’s clear he’s not going to sleep and he will be sweating and hyperventilating and I’m just not ok with that. I have another young child I can’t just leave to themselves for hours a day to deal with this. Wtf am I supposed to do. Put him to bed and let him cry forever because his teeth hurt? He also cries whenever I am doing anything around the house right now, i try to put off the things that can wait but I have to feed them and myself, I have to do some chores that can’t wait and so I let him cry but I am so drained and frustrated.
