Stuff is gonna happen! They will make incredibly stupid choices and get into all kinds of trouble. Take a beat. Be radically merciful. THAT is what they’ll remember and that is the lesson they’ll learn.
Think about building a career. Take low-paying or no-paying jobs that will give you the experience you need to build it. It's not all about the paycheck, especially when you're young and don't have too many bills to pay.
Fact: when you drink to excess you are significantly more likely to cause harm to someone or be harmed yourself. Being drunk means surrendering your ability to keep yourself and others safe.
We all have dark thoughts and moods every once in a while. That’s part of being human. But any sustained ideation or inclination to hurt yourself or someone else is a red flag and needs mental health intervention.
Encourage creativity, science and engineering: Make a craft station / work bench for projects. Fill it with all kinds of art supplies, engineering kits, tools, pegboard, etc. Stock safety equipment like goggles and make sure the area has good lighting. Lots of ideas on Pinterest, etc.
Put a few drops of tea tree oil in their shampoo bottle to keep lice at bay. If there’s a outbreak at school, add more. (Or spritz their hair with a tea tree oil solution.)
Like me, you turn to food for comfort. That’s okay to a point, but it won’t help. That hole you’re trying to fill will just get deeper. So if you can’t or won’t stop eating for comfort please consider this suggestion: Do something creative first. Sing, write, paint, run, lift, act, improv, whatever. The hole will be so much more shallow when you go to try and fill it with food. Hopefully, eventually you’ll get to the point of staying in “creative mode” to feel better.
Happiness: Someone (or some creature) to love, something to do and something to hope for. Don’t get too caught up in the rat race, money doesn’t mean you’ve arrived.
