38 years old and pregnant

I have an appointment scheduled for a medical abortion this coming Monday. I’m barely 5 weeks along. I’m 38 years old. Happily married, I have a 7 year old daughter and did not want to get pregnant again. The whole idea sounds terrible to me. I don’t want to do the maternity stuff, daycare, up all night, labor and delivery. My daughter was premature and that is a huge reason I didn’t want to have another child. My parents are elderly and have advanced diseases. I have vacations scheduled, all my friends have exited the baby stage. I’m not happy about this pregnancy at all. I’m just looking to talk to someone about it or just tell someone…. Am I being selfish? Just looking for people’s similar experiences and their experience with the abortion pills.

Thanks.
