What to do about bleeding nose and gums?

I just came here this fall. Since then, my nose has been bleeding occasionally without any injury. My friend told me it was because of the dry air of U.S. Is he right? How can I prevent this situation? I also have a problem when I brush my teeth. My gums are always bleeding and not just a little!! What should I do? Thanks.


What can I do about my food issues, exercise compulsion, and loss of bladder control?

Last year I was Teetering on the Brink and this year I've fallen off of it. The teetering individual who was worried about how much she thought about food and her weight has turned into a very scared person who has fallen off the brink, with little on her mind but what she eats, when she eats it, and how she looks. I haven't had my period for almost a year and exercise compulsively until I can't anymore, when my legs simply hurt so bad and my knees won't hold me up. Worse, I seem to be losing bladder control — several times when I've been very tired, I've wet the bed at night or been unable to wait until I got to a bathroom. I can't live like this anymore and every morning I promise myself I'm going to change but then night rolls around and I've not changed a thing. Please tell me something that will help — I never knew desperation's face was this thin.
