I feel soooo guilty

These past two years have been really hard for me. My son is 6 months old and I turned 21 when I was pregnant. My ex of 6 years left me after our son was born... and I struggled immensely w my mental health. I haven’t done anything for myself in forever. Well my best friend said we should take a trip to Florida to get away for a week. She planned it, and happened to pick Mother’s Day weekend 😭 I had no idea and I had already paid her when we found out we’d be gone my first Mother’s Day ... 😭 I feel so guilt for missing my first Mother’s Day. And I feel guilty for going at all... but I have my son 6 days a week, I work and take care of him solely. His dad has him weekends and is taking him for the week. I feel so exhausted especially after the last two years and I feel like I really deserve a break. But I worry that I’ll be judged and ridiculed for going on a vacation away from my son:( on top of already feeling immensely guilty about it. (Were fully vaccinated in case anyway says anything abt that) his father even said “you can’t feel guilty when your choosing to go have fun instead of be with your son” and I just feel like so terrible for this 😔 but after work I’m w our son everyday and even half the day Saturday like I’m a tired mama who would like a week to herself.
