Feeling Great, But For How Long?

I get this often. Having no anxiety often gives me anxiety. I think it's because I'm so used to anxiety that there's almost a hidden comfort in having it, and when I don't have it, I think something is wrong or something bad will happen. I'm always worried that if things are going "too good" that it won't last/something bad will happen because that's always been the case

I understand. When I have good days I wait for something bad to happen to ruin them. Just enjoy doing well while you can, and don't beat yourself up if things change.
