Does exercise really reduce stress? I recently took a new job that is very high stress, and I need a release. My friend says I should take up mountain biking, that it will reduce my stress (and keep me from gaining weight at this desk job). Thanks for the great site.

1) This is more of a coping question. I am a first-year who applied for a single room over the summer and was denied. I figured that everything would be okay nevertheless. I tried to look at the situation as a character-builder. Well, that is not the case. My roommate is very depressed. I talked to the RA on my floor, but she didn't take any action, except to talk with her. Unfortunately, my roommate is so ashamed of what's happening that she denied the facts, and the RA believed her. No one except me has realized yet that she is sleeping most of the day and all of the night, and that it is indeed a real problem. I have expressed my concern to her and encouraged her to go to counseling services. She went a couple of times and then started canceling appointments left and right. I have worried about her, but I have no backup whatsoever, so there is really nothing I can do to help at this point. We get along relatively well otherwise.

Right now, the concern I have is that her depression is pulling me down, too. I literally have not been alone anywhere for more than two to three minutes in weeks. I wanted a single because it's a requirement that I spend some time by myself, and I'm going crazy these days. The lights are always out in the room, and I've noticed that I'm sleeping more than usual myself as the situation has progressed. Also, I am having to deal with some personal issues of my own this semester, and I simply don't have the energy to take care of someone else who desperately wishes that I would do so. Any ideas would be greatly appreciated.

2) I know that when a friend is depressed, it's important to reach out, discuss the issue, and be there for the person as much as possible. But that's quite hard to do when I myself have a history with depression — I feel as if her emotions are taking me back to a place that I don't want to go. I really empathize with my friend and feel her pain, but at the same time know that I'd be useless to both of us if I'm in the troughs too. How can I help without sacrificing my always precarious emotional equilibrium?

What is the criteria for determining if a relationship is abusive? My husband has never struck me in anger or injured me, but he is constantly poking, tickling, flicking me, etc. When I tell him to stop, he usually says, "Why should I?" and continues a little bit more. It's like a kid tormenting a little sister. He gets right in my face and sometimes pokes me in the chest while he's telling me something. There's never any anger until I get mad at him for doing it, and then he tells me he's just playing. The other night when I told him to stop poking me, he said, "I'll do whatever I want." That really bothered me. When he does get angry, he usually just ignores me, but occasionally he'll throw something (but not at me). What do you think? How can I make him understand that his "playing" is upsetting? Is this type of behavior a precursor of actual violence?
