First time away

Headed out tomorrow for a girls reunion in the woods! I'm really excited to be around my great friends again but I am so anxious about leaving my Sept baby for the first time... the longest I have been without him is a work shift. I know he will be in great hands with my Husband, especially because he is a SAHD and the primary caretaker... but I can't help but feel scared about the distance! It is a 7 hour drive from our home and while I will have a power bank I dont even know if there is cell reception. I cant help but think if something terrible happens I will be unreachable 😰 tell me this is normal first time away anxiety
