SO away?

Tyesa
How many of you have SO that travels for work or military etc.? My husband may be away for a job for almost a year.. We find out tomorrow... I was a single mom with my first child and it was incredibly hard.. 
I am scared it's just going to be me again but now with two kids.. 
I know lots of people do it.. I know it is possible but I am still freaking out. 
I wasn't working 40 hours a week when I had my first..
