sometimes, maybe a couple times a month, I find it hard to breathe. to explain further, its like when I try to take a deep breath my heart just squeezes, as I describe it. It really hurts so I just hold my breath to avoid confrontation with pain in my heart. I'm a female and 15 years old. I have just started to hydrate myself more since dehydration is the worst. My diet is average and healthy. I stay away from pork and red meat and drink A LOT of milk. roughly 8 glasses a day.
