Feeling Bad for Trying to get some ME time

I know a lot of parents struggle with this but I have been trying to get more "ME" time. My sister was visiting from out of town this weekend and I thought what a perfect time to get some "ME" time. My mom was here, Elyssa had her cousins to play with and Elyssa's dad could take care of her Diabetes care while I was out for a while with my sister. My sister & I went to a nice dinner Friday night and had some drinks after. Everything went good so I decided to go for it again and we went to have drinks Sunday night. Well Elyssa's blood sugars went low she had a BG of 57 probably from running around and playing with her cousins. She always runs around like crazy when she goes low. I have no idea why but she does. Well she ran right into a door knob. I got home and she was sleeping. I was afraid to go to sleep last night in fear of thinking maybe she got a concussion or something from hitting the door knob. I think I woke up like 20 times to check on her. I felt so bad for trying to get some "Me" time and not being there during her accident. I wish I could be everywhere at once but I know I can't.
