Yes. Right now I'm worried that I'll be in trouble for failing to get the work done that my boss wants (he's away for 3 weeks and the work is proving rather more difficult than expected). Objectively it's very unlikely that I could be in trouble whatever happens (and I'm not incompetent at the job), and even if I lost the job it wouldn't be that much of a problem, but I won't feel able to relax until it's over.
With people, I'm always thinking that I've said or done something offensive, or not done something they were expecting of me. If I speak, I feel I'm being invasive, or I just worry I may have said the wroong thing. If I don't speak, I worry about being boring or giving the impression that I'm not interested. The better I've done at impressing somebody with my social skills, the more I worry about not being able to follow through next time. If I tell a joke that goes down well, I worry about never being able to think of another joke as good. It's as if I think people are monitoring my every action and waiting for the slightest excuse to judge me worthless. Of course they aren't, as a rule, and I know that, but all this crap rattles round my head regardless.
The only help I've found for it is to try to talk myself down......and I've occasionally found myself telling people about my plight and been given some reassurance, but that only happens with people I feel exceptionally secure with, and there really haven't been very many of those. Normally I'll just keep it all to myself....guess I don't want to be a burden on anybody.
