I went to another doctor to get a second opinion. He asked me a bunch of questions and just by that ruled out what the other doctor thought. He says that he dosn't want to rush to any conclusions but said it had to do with dehydration. Basically I get dehydrated and my blood gets more concentrated and my blood pressure goes down. Also that when it's hot outside my blood vessels constrict. So with the low blood pressure and constricted blood vessels when ever I go from a lying down or sitting position to a standing position fast all the blood goes down into my lower body and can't get back up in time and I pass out. It makes more sence then what the other guy was saying.
