Selfish mother or no?

So the back story: i work 12 hour shifts 7am-7pm but usually get off abiut 30 mins late. Then have about an hour and a half until i have to go to sleep for the next work day. I have to work all through monday. My mother goes to sleep at 8pm and lives 30 mins away. This is her reaction when i asked if we could spend mothers day together for like almost a whole day on tuesday instead of just like 30 minutes one night. Is she being selfish or am i the one being selfish bc my pregnant self needs to go to bed on time due to my insomnia?
