First trip without baby....HELP!!

So my 25th birthday is coming up and I've already planned and partially paid for a trip to NOLA for Mardi Gras. But the closer I get to the trip, the more anxiety I feel. This is my first baby and I'm freaking out about leaving him alone with his dad (even though my mom is literally 5 minutes away).

Moms, how did you get over this? Any advice? Please help because I'm 3 seconds from cancelling the whole damn thing. 😩
