Liquid coming from ear

Im 14 and im worried about my well, brain really. Sometimes I feel a liquid coming out one or both or my ears, its not blood, its almost like water. When i stand up i get a huge head rush. I've had no experiences with blood, and i dont get major headaches. Its really starting to scare me but im too scared to go to the doctors incase something is really wrong. If you can help me please do because im really starting to worry.
