You're doing a great job, you know.
With all the pressure you've got on you, you're still holding everything together. And figuring yourself and everything else out. Maybe not as fast as you want to, but you're getting there.
You think you're yelling too much, but all your kids are going to remember is the laughing you. The embarassing-dancing you. The popcorn-for-dinner you. The you who loves them more than they'll ever know, unless they have kids of their own someday.
They know you're amazing. I know you're amazing. You probably know you're amazing, too. It's ok to admit it, especially today.
