I was out shopping and all of a sudden I got super light headed, the sentences I was saying were not making ant sense. my legs got super shakey then I passed out. when I was coming to, I was really sweaty and could barely hold my head up. I m not pregnant, I don t have any eating disorder , I don t do any kind of drugs, only ciggs. this is not the first time this happens. its uncontrollable and it freaked me out that I wasn t home but in public! what could be wrong with me?
