Is it okay to feel lightheaded and dizzy after physical activity?

1) When I do a 3-mile or 5-mile run, I run for time and try to finish with nothing in the tank. The closer I get to the end, the more I push myself, because I know I don't need to sustain the effort much longer. When I stop running, I suddenly get very light-headed and dizzy. It never happens while I'm running. I walk briskly while I'm warming down, but that doesn't prevent it. Why does this happen? Is it dangerous?

2)  Sometimes after jogging a while, or cycling a great distance, my head begins to spin and I feel as if I'm going to pass out. Is it normal to have feelings like these, and if so, how intense should these feelings be?


What about emotional abuse?

I notice in your mental health section, you only have info on sexual abuse. What is emotional abuse? I've heard a lot about it lately, but it doesn't seem very real to me. How can simply being called names, or whatever, be as devastating as people say? Short of being threatened with murder, what people say is just words. I can't seem to find very good articles about emotional abuse on the web.


Is hypnosis an effective form of therapy?

What is your opinion about hypnosis? Is it dangerous? Does it really work? I have a few issues about my personality that I would like to work on and the more I read about hypnosis, the more I think this is what I need. It almost sounds like magic to me. Would this kind of therapy help me with my many problems such as: self-confidence, communication problems, control of my emotions, sexual intercourse pain, etc.? As you see, I have quite a few things to work on and I really hope that hypnosis will help me. However, I wanted to get your opinion about it before I go ahead and do it. Thank you very much for your wise advice.


How do I begin to talk with my children about sex?

I have three young daughters (ages 8, 6, and 3 years), and I know that it is about time to begin teaching them and talking to them about sexual issues. But my mother never talked to me about such things, so I really don't know where to begin. I do need to do it soon, though, because I was molested as a child and I don't want my girls to go through the same thing, you know, thinking they have no one to talk to about such things. Because my Mother never believed me when I told her that someone had molested me, I want my girls to be able to talk to me about anything. But I am very shy and easily embarrassed by certain issues, such as sex. How can I overcome this, and how do I spark a conversation about sex with a six-year-old, what should or shouldn't she know, and how can I explain things so she will understand? Same thing for the three-year-old.


Why did she break up with me?

I don't know what I did wrong. My girlfriend of one and a half years broke up with me out of the blue. We never fought or argued. I asked her why, she said "I don't know." I asked her what did I do wrong and she said "nothing." She was my first ever girlfriend and I was planning to ask her to marry me. I don't understand what I did wrong. There has to be a reason. Why won't she tell me?


Why do some people gag when someone is vomiting?

Why is it that when a person vomits, it causes others to vomit — even when they don't have an illness causing it? Is this something triggered by the brain or is it something that happens by reflex (survival instinct) for someone to vomit since, perhaps, what the first person was eating may affect the second who vomits as well?


Can our relationship survive summer break if we haven't had sex yet?

I am a 19-year-old college student and am seriously involved with my boyfriend who is a 20-year-old college student. We have even talked of getting married someday. Our relationship is very close and we talk about everything, and he is very wonderful and supportive. I feel very committed to him and would really like to have sex with him. We have tried twice, but it hasn't really worked out because my vagina is too tight. I am pretty sure the problem is just that it needs to be stretched more, because I have been to the gynecologist and don't have any infections. He says that he is okay with whatever we do and that he loves me no matter what, but I still feel guilty about not being able to go all the way. How do I get over this guilt? I will be leaving college for the summer soon and we will be separated for awhile and I want to make sure that our relationship is as solid as possible before I leave so we have the absolute best chances of surviving the summer!
