You need some quality sleep. I had the best night's sleep I've had in a VERY long while last night.I wish my dreams weren't all violent/scary/whatever. Like, its not enough to where I don't want to sleep or are afraid of them or whatever, but they all consist of these high stress situations where I'm having to fight/run/whatever and waking up with fight or flight fully engaged makes for some really unfortunate, easily avoidable arguments when I'm already on edge from the start. I wish people would get that and could just give me space to breathe and get to a normal heart rate before trying to talk to/criticize/get me to do stuff cause me already on edge and then immediately getting fussed at means I'm gonna be defensive af or lash out because I've literally been fighting off bad guys or having to help kids get away from someone or been hunted and my fight or flight response is already going full blast. Ugh. I'm just so tired of everything.
I won't pretend to know, much less understand your situation, but with my current, far less than stellar situation, that night's sleep sure as hell made today a hundred time better in outlook and physical well-being.
Naturally with kids, it will need good planning. Right before I went to sleep, I ate a bowl of ramen noodles with a nice chunk of canna butter. Yesterday was a Mfer for pain and everything was a mega chore. I had things that just had to get done, so I fought thru it. Canna only took the edge off the pain. Any more canna and I'd be out. So the sleep was very welcomed.
Woke up feeling MUCH better mentally and physically! While my problems, real and perceived are still there. They are NOT in the forefront of my thought processes. I feel better physically too! BOTH improvement are WELL welcomed.
It's something ya might want to try.
