Keep him in your thoughts and prayers, be positive, he needs you to be strong also! He will be hanging out for news of home so keep this positive and cheerful. Time passes more quickly if you are busy so get involved in what ever it is that makes you happy! Maybe there is a charity you like to support which could do with your help during the time your son is away that would make your days full, and take your mine off negative thoughts? It is a very difficult time I know.
Love your quilt!
Take care
