My husband says there's nothing we can do, so I just have to deal with it. You carry a tremendous load, and consequently may feel lonely, sad, angry, or resentful. These feelings are certainly normal under the circumstances. It's important that you find something to do that feeds your soul, whether it's taking the kids to the museum to look at something other than their fingerpainting, or writing in a journal when your kids are asleep. Reach out to others.
Isolation can be dangerous, and can lead to feelings of loneliness and despair.
Sharing your concerns with others in the situation can be an enormous relief. You need to have your feelings validated, because it may often seem as if you're the only one going through this. You're not alone, but the trick is finding others with whom you can develop a relationship, spend time, and share stories and concerns. Perhaps you can attend a social event to meet other military wives. You might be surprised at how comforting that can be.
