How did you survive not living with your kids when you got divorced?

I have recently been divorced. I can’t seem to function with out my kids. I spend all my time thinking about them and the next time I get to see them. I finally broke down emotionally to my brother and his wife and just bawled my head off. They are 7 and 5. People keep saying it will get easier. I can’t fathom a time when not seeing those two precious gifts every day will get easier. Please help and let me know how you survived.
