being upset

Ladies,
What do you do to calm your self down if you get really upset? My SO really let me down this weekend and I was a mess last night & early this afternoon when him and i tried to "talk about it" just turned into fighting. I know its unhealthy for my baby, I got it together pretty quick but I still feel really upset and mad inside. I went for two walks, took my son to park, ate some chicken wings lol, but i feel it building up inside me still. I need a hug! Lol 😞
Ps- this huge type of fighting doesn't happen a lot and i plan on working it out with him, so leaving isnt happening...yet. I just feel depressed and scared I hurt her some how being so upset.
