I just took a got shower and suddenly started getting a terrible taste in my mouth, my legs started feeling weak and my body felt heavy. I partially couldn't see. I couldn't function...I tried taking out my contacts and I tried putting my shirt on, but both were nearly impossible. My heart started racing, my body almost felt numb and there was a tingling sensation...I haven't ate breakfast and it's 10:48 AM. I'm on my menstrual cycle...19 years old...this has always happened since 7th grade...i already went to the doctors and it's not anemia.......what else could it be?
