My life is a constant stream of worry and regret. I know neither of these things are helpful. I know they only make me more miserable. But I also know I am not able to stop either of them. Some people say they are, and I have no reason to doubt them, but I am not. And yet, everyone I've ever talked to tells me I am wrong, and that I can stop both harmful thought processes if I A) want to and B) try. The one thing that *everyone* lacks is a clear instruction as to how to do it. Part A is easy. Part B is a total ****ing mystery.
Logic says that if other people can do it, I should be able to do it also. But here I stand, unable to do it. Thus, either everyone who says that they can stop worrying or let go of regret is lying or wrong, or logic is not always a reliable indicator of reality.
Man, I'm not criticizing or judging in any way. But if it effects your life for the worse and the burden is too much they do make medication for that. There's no shame in it if it helps. It's all good, man. My sister has OCD (and I know that's not what you have) and I've been telling her for years that she doesn't need to suffer alone.
And sorry if I read too much into your post. I'm not judging.
