I'm stuck I froze and I don't know what to do

My partner is really really mad right now to the point where he's slamming doors and throwing things (but not at me) in the apartment and the neighbours can probably hear. For some context, he couldn't get any sleep last night before work and blamed it on me and his mother for being too noisy, I f*cked up his meal for work I didn't realise I undercooked it (rare beef) until he told me at work, not to mention I accidentally gave him a small burn while holding a hot pan (nothing too serious, he wasn't mad about this) and today he lost 200 dollars from a skin checkup, again blaming me because his mother is apparently paranoid about some skin condition that runs through my family, and scared that I'll pass it on to him (fyi, I don't even have this condition). Turns out she was paranoid for nothing and it was benign, so it made him even more *** to pay 200 dollars for nothing. And now because he's so mad he can't get enough sleep for 2 days in a row now making it worse.

I'm honestly stuck, all I can tell him is that I'm very sorry for what I did last night. I normally don't make these kind of mistakes. I tried to give him some space because he was absolutely furious but just as I walked away, he mumbled something like "as usual, you're no help" so I went back and tried to console him, which obviously did nothing. I honestly didn't know what else to say in that situation as I don't know what else to do or say that could have made the situation better, then as he walked away he starts saying "there's no point, nothing will get through to you anyway....nothing changes". I sat there for a minute or two to soak that in, because I have absolutely no idea what other horrrible thing I've done other than what happened last night???

All I can think of is, he's always had a problem with my lack of awareness with my surroundings (among other things) or my brain shutting off on certain occasions but I feel like I've somewhat improved and it's not as bad as before. I feel like I made a simple mistake that will just blow over but clearly there's something else on top of it that bothers him. I don't think I did anything this morning that would have bothered him, because I was just sleeping?? Then I woke up and all of a sudden he was already giving off a negative vibe before he lost it....

I've always had a massive issue with confrontation. I just shut down whenever he's *** because I honestly don't know what to say. If I ask him to tell me what's really wrong he might just tell me again that "there's no point". Honestly I'm *** terrified, that's like opening a big can of worms or diffusing a bomb if I ask him to tell me..or worse, he might start throwing things again and shout at me. Right now I've just clammed up completely, fully silent and I can feel him looking down on me. My partner has told me previously not to do certain things around the house that annoys his mother or him, but afaik I haven't done any of that in a while..or am I absolutely blind or stupid to realise what I've actually done other than what happened last night??? It's not that I don't listen to whatever he says, sometimes I just slip and I don't mean to make either of them upset. I feel like I've improved in some way, but it's clear that I slipped up again. Even worse, his mother hasn't really liked me for a while, but I've tried my best to not do anything she wouldn't want me to do around the house. I'm just absolutely stuck, and I feel so *** horrible about this. I feel like I'm the worst partner ever and he's right, I'm absolutely useless and not helpful at all.

Sorry for the long rant, I don't know what to do and I'm absolutely terrified.. I want to leave this house and go home but it might look like I'm just running away from this... all of this sucks because we had such a nice weekend together, he's been in a very good mood the past few weeks until all of this *** happened.
