I cannot sleep because I have ocd about the thought about being able to control my heart with my mind and it freaks me out to think that I can make it flip out with my mind, and on top of that I hate the butterfly sensation in the stomach when getting anxiety because I feel it so intensely. I get so anxious that my left arm starts to hurt and I experience nausea, another thing to worry about. Maybe my stomach is just upset. Somebody help
