Scary and sad month or more to come for me

So me and my family live in pa. This morning my husband got called out and had to leave for Florida for hurricane Irma l. He works for a tree cutting company that has contracts with electric companies to go out, climb the trees or go in those bucket things on the truck and cut a mass amount of limbs off, cut up all trees that are already down, or even just cut the whole tree down if it is damaged depending on where the power line is located to the trees. I'm sad because he will be gone for over a month as it is routine for when he goes and dose these jobs. Don't get me wrong he is doing this so others can have power, can drive safely without a tree falling on their vehicle and he also loves his job. He will miss our first and second appointment for our second child as well as our first scan so it makes me feel sad and anxious as I will be taking care of the other four children alone. Also our 4 1/2 year old is addicted to daddy and is use to seeing him every night and have 3 days a week to go fishing or just work on their dirt bikes. Now he is going to be confused as he doesn't remember when this happened last year for hurricane Matthew. I'm scared because for one he is no spring chicken anymore lol (41) and his life is in danger every day but add a natural disaster and the risk which is normally 45% is now at about 75%. So much more can go wrong when he is out there. I am trying to not work myself up or think negative or about different bad scenarios but it's so hard when I am already hormonal. I have to put on my big girl panties, keep a smile on my face for the 4 children and just push through I guess. Sorry this is so long. We haven't announced yet and won't until right before Halloween and I just needed to vent a bit and get my worried out.
