Friends, bad years, and direction

I have some of the greatest friends you could ever ask for. I'd have gone insane without them around here. But there's a problem... We're all unhappy, this year has been awful for pretty much everyone I care about. I have one friend who's far too familiar with losing people. Her best friend, and the person who actually made her less than perfect life happy, is leaving on his mission. Since she's bad at losing people she managed to end things on a bad note. She talked to me and she felt better for now, but she's still losing someone she loves again. Then there's another friend, I'd rather sit and do nothing with her than do something insanely fun with anyone else, who thought she was going to get money her parents owed her so she could pay for the second semester. But it turns out that her parents have money problems, and no one has been telling her what's going on and things have gotten steadily worse since she left. And now she's not getting her money and she feels like she should be at home helping her family instead of here, and she really doesn't like the idea of taking out a loan. Then there's another friend who I got really close to who, then did something that really hurt and betrayed me. She didn't mean to, and she really feels bad for it, but we've tried being friends and she's never really going to let us be friends again. She's miserable as well, but she won't talk to me about it anymore, and she's told me I was better than anyone at understanding everything. So she's down someone to talk to and depressed. And there are a half dozen other stories I could tell you. Everyone of us has talked about how we've no idea what we're doing in college or what to do for a living. Is it normal for this many people in a group to be unhappy at once? Does anyone have any answers? I just really hope this next year goes better for all of them.
