Hello minus1: I recall reading your introductory post. From what you've written, both there & here, it sounds as though you are & for a long time have been struggling with a rather large boat full of anxiety. This is something I've struggled with for many years as well. I've also had those same annoying thoughts you mention in this post. I have also pretty-much always felt an almost overwhelming urge to jump whenever I've been in a high place such as a tall building or a cliff edge. Plus I've also always struggled with agoraphobia & glossophobia (fear of public speaking).
I don't know what the remedy for all of this is. In my case I mostly just toughed it out until now I pretty-much just keep to myself. That works for me though because I'm an older person now. In your case, perhaps you may want to consider seeing a therapist or possibly trying some additional anxiety-controlling medication. I know how difficult it can be to live with this kind of anxiety. I wish you well...
