Pregnancy brain! And starting to feel too anxious!

So today was a terrible day!! I just need to get it off my chest! I've been watching my niece and nephew for extra cash this summer to get thing I would want for the baby but not necessarily need, BUT idk if it's worth it! Ugh I love them but they are so rude always complaining and making comments about anything we do! Today was a rare day and I had 3 appointments (I have PT 3x a week @ 10 which the parents were made aware of prior to me starting care) on top of my usual appointment I had an emergency prenatal appointment for mild spotting and another appointment after that. So needless to Say my day was packed but this doesn't ever happen so I had the kids stay with my mom while I sat in at appointments all day which my family was also made aware would happen if I had appointments and were fine with .... Well when I went to pick them up I discovered they hadn't eaten lunch all day ... I asked my mom she said she asked them numerous times to eat each time they said they weren't hungry so they didn't eat well my nephews guardian was pissed but like the kid is 7 if he was hungry he'd eat ... Even when I worked in child care we never force fed kids so yeah that sitch got me all anxious making me feel like idk what I'm doing even tho I've worked in child care for 10+ years and have a job with the school district as a special education aid ... Then at dinner I totally spaced and left fries in the oven and almost burned the house down ... And hubby obviously wasn't happy ... I'm just starting to feel like a failure and like I'm not capable of anything because I want to please people and have everything perfect all the time and even tho Ik it can't be its eating me up plus being 30 weeks pregnant is only making me fear what mistakes I could make with my newborn and that scares me even more! Ugh anyways thanks for listening ladies I just needed an outlet!
