Besties bachelorette

So my best friend is having a 2 and half day get away for her bachelorette in New Orleans. I’m in Texas. I have 3 kids. 8,5& 8months. I work a lot and cherish my weekends with them and my husband! But i want to be there for my friend who was there for me when i was getting married and having these events. I’ve had a lot going on with a sick mother in law and other things so i told her i wasn’t going to make it but i feel horrible. Opinions on if i am in the wrong for leaving my family for a weekend. (If i changed my mind about going)
