Can anyone help ???????????????????

i asked this question earlier but when i click on it to get my answers yahoo says its been deleted. i need to sleep all the time at the moment, my periods have disapeared (im not pregnant as im not ually active and havent been for over a year,) i cant seem to do much without getting out of breathe, my ears seem to be constantly ringing, getting pins and needles in my arms and legs. my brain seems wooly a lot of the time and im feeling lightheaded and dizzy a lot. ive also put on a lot of weight recently without my diet changing ive got hair growing on my chin (not pleasant for a 25yr old woman) my motivation to do anything seems to have disapeared. what the hell is wrong?
