Hello my name is Kayla. I don't quite know where to begin But I'll start by saying that Im only 16 I'll be 17 in December. Recently we discovered that I have ao prolapsed valve which caused the heart palpitations, shortness of breath, feeling winded that I was complaining about. Now my mom says I have the flu, but I dont think I have the flu really. Everything is foggy, my limbs and everything else feel weak or a little heavy, but I dont even have the usual aches and pains accompanied with the flu. Please tell me what could it be? Just typing this is taking alt of energy
