How do you tell if a friend has depression?
I'm on a year abroad at the moment and I've got a group of friends here who are also on a year abroad. Most of us are having a great time but one is really miserable - she never wants to leave her flat, spends every evening on Skype with her family/boyfriend back home and is always crying. At first we thought it was just homesickness but she's been like this for months and almost didn't come back after Christmas. Is there something we should be doing??!
