How can I (29f) get space without running away or looking crazy.

To make it short I’m having a very stressful time, a lot of bad events happening in my life in very short succession. I went numb a while ago and now I’m passed that, I almost feel in flight or fight mode.

I really need some space, from everyone ideally. I have 2 children (9&1) so I can’t just up and go. My anxiety is at an all time high. I think what would help me is getting away, even for one night. I have no family of friends. I really think I am on the verge of a breakdown. I’m at home but I just want to be away from here. I need quiet and peace and my own space to breathe. I thought about a hotel for a night but I think that would make me look a bit crazy? I wasn’t going to tell anyone and go to my night shift like usual. But secretly book it off and go stay at a hotel, order food, watch tv and get a full nights sleep, I haven’t been able to because of my 1yo, I haven’t slept one whole night for like 18 months. How can I do this? Will my plan make me look suspicious or something?
