First night away

So my sweet boy is 8 months old and I’m gonna be spending the night away from him. Tbh it makes me really sad.. I never want to be away from him. I see moms posting all the time how they always want a break or a night off but I never do! Even going to the grocery without him feels like something is missing. Anyways, I don’t know what to do to distract myself. I have a wedding then I will be home and my husband will be away too. How do I not fold and just go pick him up once I’m home? He will only be 20 minutes away at my parents but this is me trying to ease into it because we are going on vacation for a week without kids in January. Any tips would be amazing and am I crazy for being so anxious about it? TIA 🤍🫶🏼
