Hi Angela
I'm glad to hear your pregnancy is going well! You had some rough times at the beginning, so I'm glad that things are calming down.
I am so sorry to hear about your grandfather. Its really hard to watch our loved ones get old. Its even harder to come to terms with it when its their time to go; however, I think its even harder to see him suffering. I hope that everything works out for the best. Its not fair for your mom and grandma to expect you to pull strings for your grandpa at the hospital. Nothing makes people angrier than when someone else tells them how to do their job.
Don't feel guilty for taking a day off. Sometimes we need that, and cleaning the house (at least for me) can be very gratifying and calming when stuff is stressing me out.
