I'm going through a divorce & I'm terrified! Any positive quotes for me to help me through it?

I'm going into uncharted territory, I'll be a single mom of 3 kids ages 4, 3 & a 3 month old. I'm really scared, bc we split up a little while ago, but signing the papers makes it so final, and Idk what to do with my life now! All my future plans were with him, so now I feel like I have to reinvent myself. My kids are #1 always always always... but just... now what? Anybody have any positive thoughts, quotes, affirmations that may help me?
