Something that helps me a lot is reminding myself that we all tend to evaluate our own actions under a microscopic lens, observing problems that others would never pick up on because they’re not looking at us that closely. We tend to be much more critical of our own actions than those of others. And everyone does it! So reminding myself of this fact helps prevent me from spiraling.
ALSO: It can be very helpful to bring up a concern about something you did or said to a friend who was present at the time. 9/10 times they will tell you they hardly noticed it (if at all) and that it did not come off the way you feared. True friends will always accept you as you are and, as much as your anxiety brain would have you think otherwise, do not secretly hate you or think you’re lame!
