What works for you?

I’m looking for some advice from other parents on how you regulate your emotions when you’re extremely overstimulated with two little ones. My husband is out of town for a month, everyone I leave my children with is out of town) and damn. I caught myself nearly snapping yesterday (I really make effort not to yell) and I just wanted to scream. I realize I need to do a better job at being able to regulate my emotions, so I am looking for some tips that worked for you. My kids are young ( 1 and 2 ) and we live in a remote part of Alaska. Being outside isn’t an option as it is -50°.
