I have this recurring overwhelming feeling that I might all of a sudden lose control over myself and my body. Not sure what that would look like. It usually sends me in a panic, especially if I'm in public or in a bus, train, etc since there are other people around. This sensation doesn't last long, but it happends pretty frequently. It's like I have a bomb in my hands that could go off at any moment. On the outside I always appear calm and in control and nobody could tell the chaos I feel inside..
