Ok, let's start with the "red mist". Have you mapped your moods to your menstrual cycle? That could be a game changer.
Next, your family of origin has some red flags around it. Were they fine with you moving out at 16 and having 3 kids by 20? Under normal circumstances, that would be a very, very unusual thing to happen.
Your family/home life sounds busy, stressful and you sound overwhelmed and fed up. Do you ever get time out and away? Have you ever had some nights away, just you, to rest and recuperate? Does everything fall on your shoulders?
Finally, your husband. You have a house full of mess and stroppy children/teens, aren't coping, and he just fucks off for a jolly day out. He doesn't sound that great, OP. He sounds lazy and entitled. A "good" man would roll up his sleeves and get in there with you, not leave you to deal with it all.
TBH, after a lifetime of the above shit, I'd be fed up and fucked off too. 🤷♀️
