guilt, its whats for dinner

MIL is in the hospital. i am sad to say that my first thought was please do not let this ruin our trip to dis.ney. followed immediately by guilt. how do we learn guilt? how do you find the balance between living and harboring guilt? am i an evil biatch for wanting to experience dis.ney with my kids without a dark cloud following us around, or worse not being able to go at all because of untimely events? guilt, its whats for dinner.
