| | is this normal? HELP!
I am an 18 year old female- I am 95-100 pounds, 5Ft 2In. My Blood pressure is about 94/56 and my my heart rate is about 86bpm. Recently I have been becoming dizzy/lightheaded, and not just when I get up or sit down, sometimes after I walk for a minute or so (sometimes just when I cross the room) Yesterday I nearly Blacked out when I got out of the shower. My ears where ringing (so loud that I was wincing just at that,) and everything went black, except for the tunnel around whatever I looked directly at. I felt like I was about to start sobbing (really hard) and I didn't know why. Then as my vision started to clear, I saw little grey and purple blobs over everything I looked at, and I began to feel really (really) naseous, and I had to sit down(so I wouldn't fall.) Afer maybe 5 minutes my vision cleared the rest of the way, as did my hearing, and I could get up without feeling like I was going to throw up my entire stomache. Thats the first time anything that serious has ever happened, but I do always get dizzy and lightheaded, (I have also felt really weak for about a month or so) I know this is long and confusing, but I am concerned. HELP!
