You know, it's a funny thing being gone from home so much. While I'm gone long term, I usually can't wait to get home. After I've been home a few months, part of me craves to be gone again....fully aware of the fact that I'll want to be home as soon as I get to where I'm going. You get used to homesick and missing family and friends, it just takes time. It never goes away but it gets easier to deal with.
What really helps is having your brothers right there with you....my other family.
