I've been away from my home because I need to work so I can give them something. Being comfortable once you're in the place you call "Home" is something else. It's also a good feeling when you are with your family and you laugh together. I miss them, I don't even know when I will be able to return to my place of origin.
I hope you manage to return to your home someday, but whilst you're elsewhere maybe you could find happiness and contentment through other activities and thoughts. I wish you luck.
