My husband brought home 4 cats from the shelter last night and I instantly felt like I was losing my mind. Is it temporary or if I sober up after my child goes to bed will it be gone for good?

Feeling really overwhelmed, my brain feels very cloudy and it's hard to think and make decisions. I was getting ready for bed and I opened my computer to ask this question but was going back and forth on what to do for so long I forgot what I was doing in the first place. I never thought I was a hoarder but these cats are kind of making me feel like I am. I have always been very tidy and organized. I'm a bit of an anxious person, being in a cluttered environment makes me feel terrible. Feeling overwhelmed to the point where I'm not thinking straight. I've been on Google for 2 hours, I think I need 4 litter boxes and I already have 2 in my garage. I don't know what to do with them yet but they're in a dog crate in my living room. We need one for the upstairs and one for the downstairs and then 2 in the garage? Is that right? What if I keep the 2 in the garage but bring the one for upstairs and downstairs in the house so we can watch them and socialize them? And then after a while we can move the litter boxes in the garage? This is so stressful and I'm feeling really anxious. What do I do? And are the cats going to want to cuddle with me or sleep next to me or anything like that or are they just going to kind of just exist in the house and use their litter boxes. I don't know what to expect. I only have a couple of hours to sober up before my child is going to wake up and how am I going to explain all of this to my child? They just love cats but they won't even know where to start and I don't even know where to start so I have to sober up first. There's a couple of things I know for sure, we need to get a good vacuum and one of those devices that picks up hair. We need a different food and water dispenser because the one we have is too small for 4 cats. We need scratching posts and a couple of cat trees for them to climb on. We're going to have to set aside some time to clean up after them. I don't know them well enough to know what their personalities are like so I don't know how much time we will have to devote to them for them to feel loved and cared for. But I need to sober up. Then I can think. But I'm getting really overwhelmed and I just feel like everything's really cloudy and it's hard for me to make decisions. The cats just kind of showed up and I don't know what to do with them.
