i had a bad thing happen today. i was outside visiting with friends and i started to feel light headed. I dismissed it because it wasn't all that bad. then i started to feel sick like i was going to throw up, but i didn't. then i felt like i was going to faint, but i didn't because my husband got me up and in the truck. when i stood up, i could barely walk straight, i was slightly confused and my speech was slurred. i thought i felt clammy but he said i wasn't. he also said i had no color and my lips were totally white. he got me some water and we went home and i took a nap for a couple of hour and now i feel a little better. what happened? and should i have gone to a hospital?
