What do you do if you feel suicidal and don't have anyone to tell?

Sometimes at night I'll have a dream, and then it'll happen! There's no knowing if or when it will happen, but if I have a realistic dream one night, it's bound to come true at one point or another. For example, in first grade, I dreamed that I was in a place I had never seen or been in my life. I didn't even know it existed. Then, in third grade, I walked into the room that I dreamed about in first grade. It was the computer lab of my new school. Or I could be walking down the street and meet someone I have only met in a dream, in the exact same scene as the dream. It is all very confusing, and I think it may be either some sort of precognition or a mental disorder. Could you please tell me why this happens?

I want to become a male but I'm trapped in a female's body. I recently saw "Boys Don't Cry" and everything Teena felt I felt. Becoming a male would make me truly happy but I'm hopeless and desperate for a first step to take. I only cross dress in privacy and around my close confidants. My mother would die if she found out. Lately I have been feeling suicidal over my complete and dire unhappiness and uneasiness. PLEASE HELP ME!

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?

Recently, I've noticed that my one or two of my friends have taken to cutting themselves. I'm concerned for them... but I've done the same thing in the past and they know it. How do I confront them without sounding like a hypocrite?
