UPDATEAm I selfish for thinking like this?

I live with my parents and my 4 other siblings, my husband and our 2 kids plus one on the way. My brother has bowel issues that he can’t control. I have a ton of schoolwork due this week and I’m really stressed out. Because if I don’t finish it I fail the class and get put on probation with my school. I JUST got my 11 month old son down for a nap and usually I take a nap same time he does because I’m pregnant and tired 24/7 not to mention I have been having horrible nightmares that make me feel like I’m not even sleeping at all. So I’m sleepy. But my mom and my older sister had a doctors appointment to go to that is like an hour away. My brothers school is 25 minutes away from me. And I’m gonna go get him. I’m just a little irritated because my son only takes one nap a day. And it’s usually an hour long. And I JUST got him to sleep like 5 minutes ago and I’m gonna have to wake him up to get him in the car and then he’s gonna be fussy and mad and not go back to sleep all day until bed time.

Also: my dad and husband are at work. And my other 2 siblings and my 6 year old are all at school.

Am I selfish to be irritated?

Update:

Thank you for understanding. I don’t mind going to get him. I know that it’s easier for me to do it because everyone else was and is busy. I guess I was just really wanting my son to get a good nap in. And I wanted to get some quiet or “me” time before everyone came home and things got hectic but I just got home and my brother went to get cleaned up and watch a movie in his room. And my son is laying down in his playpen with a bottle so maybe (fingers crossed!) maybe he will take a nap. And not be fussy later. And then I know my husband will handle the kids later on so I can catch a small nap when he gets home.

I’m gonna make another post to ask about nightmares during pregnancy if anyone has any advice.
