On mat leave 8mo DS, plus 13yo DS DH works away at least one night a week. He has left this morning due back tomorrow night then will be away again Thursday morning until Friday night 
Yes I know lots of other people have it much worse than that, yes I knew all this before we married/ had DS2 etc but every time he leaves and I know he isn't coming back that day I just slip into despair and depression that I will be on my own all night with the baby.
