Hi ~ I figure it's a combination of all of it. I'm sure you're somewhat depressed, but I'm also sure you miss your husband and family. It's hard to live the way you do. Anyone would feel "down" when they haven't seen their husband for 6 months! And this is probably going to be a "normal" thing for you.
Can you go see your family? When is your husband coming home? If he's not coming home for awhile, why not go see your family? I would. I'm sure it would make you feel better just being around people who love you! Go ahead and go!
When you get back home, I'm sure you'll feel better. And if you don't, then you'll know that you have some depression. I wish you the very best. Please keep in touch with us. God bless and please take care. Hugs, Lee
