For the past week I have felt completely out of it. Feeling dizziness, can't breathe, tired. I tried to brush it off, thinking maybe it's just an anxiety attack. Yesterday I was admitted to the hospital because I was having chest pains and a burning sensation in my chest, and I literally thought I was having a heart attack. They took a Ekg and X-rays but said everything came back fine. & they told me I had costochondritis and gave me medicine for it. I feel a little better but, I can still tell something isn't right. I still feel like my heart isn't beating the way it should, I feel like I'm choking, and I could faint. I hate feeling like this. The only time I feel good is when I'm alseep, and it takes me forever to get to sleep. It's a shame, someone please help!!
