Let's start from the beginning I do have anxiety disorder I experience this feeling almost every day. Right now I am being treated with medication for it. If anyone feels that they might have this disorder please talk about it, there is help out there for it. Also, this can affect children as well as adults. Do not be ashamed of it please. More people than you think are in the same boat trust me. I kept this hidden from everyone, as soon I started to tell people. I had a lot of support.
