I’m parenting as in most things, staying calm is more than half the battle. Practice keeping your cool in all situations. No yelling blaming freaking out or meanness. Calm rules the day.
You can’t selectively numb feelings. The inclination to drink, use, shop, gamble, etc. is real but it’s a lie that it will make you feel better. Numbing makes this much, much worse. So feel! The good, the bad, the scary. Talk about your feelings, write about them or create something from your feelings. This is how to process in a healthy way.
Everybody emits energy. What sort of energy do you want to put out into the universe? Your thoughts, actions, prayers, struggles, laughter, etc. that’s all you. Your energy is all your own. Spend some time thinking about what kind of aura to want to have.
When you feel hopeless that’s when you know it’s time to seek help. It’s a red flag in someone’s demeanor. Notify parents if you notice this feeling of deep despair in yourself or someone you know. Help really does help.
Institute “Family Night” a screen-free night of games and fun and togetherness. Can use these times for conversations about things you want to address / teach. Maybe make theme nights and build around a lesson so it’s fun and enjoyable.
Continue through school years.
Practice sitting and standing "like a statue" to teach them how to be still. Start with a goal of 5 or 10 seconds, gradually move to 2 minutes. Same thing for "silent game" to teach them how to stay quiet when they need to. Bribery helps teaching this concept!
