I am Stressing myself

Yes I am stressing myself. Since I found out that my mother already have the schedule for her schedule in US embassy here I am can't help it but to think. I am worried what if, what if. I know I have to think positive but I have been waiting for this for a while now. I am thinking about the money, places where they are going to stay while in Manila. Will my mother can handle the stress during her interview. All of this are stressing me. I can't sleep well. I always get up early now. It is not affecting my job though. I am trying to stay awake as I can.
