How do I wait???

Had my gender scan (paid for at a 3D clinic) about a week ago and they said boy (at 14 weeks)! However, I'm waiting for my anatomy scan before we get too excited. I've scheduled the u/s for March 30th which is three and a half weeks from now. How does a person wait without going crazy??? 😜 I know I have no choice but to wait but I'm too excited!!! I'll be 19 weeks then.
