What is the difference between grief and major depression? A few months ago, my boyfriend died in a car accident. Lately, I have been very depressed, but I am not sure if it is just part of the normal grief process or if it is depression.

The mother of one of my best friends from high school was diagnosed with liver cancer a few months ago. She is quite ill and in a lot of pain. She's been in and out of the hospital lately and things don't look so good. My own father was diagnosed with prostate cancer a year and a half ago, but he is really doing quite well (with medication, treatment, etc.). My friend's mother will probably be dead within six months to a year, so I'm not going through an immediate crisis.

My question is: What things should (and shouldn't) I be saying to, and doing for, my friend? I try so hard to be there for her but I really don't know what she's going through. She is very matter-of-fact about the fact that her mom is going to die. But I'm sure there's something I could be doing, isn't there? I hate feeling like I'm actually making her feel worse! Could you give me some idea of what she might be going through right now and how I could help? Even if it's a method for taking her mind off it occasionally (if that's a good idea).

The last week or so I've been having anxiety attacks or at least that's what I think they are. I've been tossing and turning at night. We have just moved, which isn't unusual. My husband's job moves us around a lot. I've never had this problem before and I'm starting to get worried. Should I see a doctor?

My oldest daughter died in a motor vehicle accident seven months ago. I have a husband and three other daughters. I am very depressed. Some days I think I won't make it. Some days I don't want to. I know that my life has been changed forever, but what can I do to help ease the pain — and to help me "move on" with my life?

I have been having very disturbing dreams about a past relationship which ended over three years ago. These dreams affect my moods during the day and give me a depressed feeling. I am currently on an anti-depressant and in therapy which have helped with this situation, but the dreams are lingering and creating more anxiety for me. Any suggestions?

Whenever I am in a very stressful situation such as an approaching big deadline, my body gets unusually tired and sleepy regardless of how much rest I get. I sleep well but it never seems to be enough. Why do I get so sleepy and what can I do to prevent this change when stressful situations approach?
