Friendly reminder in case you forget between now and your next existential crisis: you're doing okay. Love and play with your kids. It's medicine.
Don't get too hung up on other people's emotions as they don't dictate your own (and not should they). Their feelings are not an attack on you. So just be there, man.
You have the ability (and have always) to create beautiful things with other people. Go do that. It's medicine.
Avoid things that are marketed to you as medicine. Unless you have high blood pressure or an infection, medicine isn't a pill. The pill is only a mask, and it's more fun to build your own mask instead of swallow one.
