All interactions with others are so painful

Even if the interactions seem good. I worry myself sick thinking that I offended them or hurt them or something bad happened because of what I said. It is so hard to live like this. I feel so awful.

I'm wondering, are you in therapy? If so, definitely bring this up.

I do a lot of "realism testing." Instead of focusing on what might have happened, I try to break down what actually happened to see if my fears are justified. Usually they aren't. It takes practice - that's why I asked about therapy. It's pretty terrifying, because there is always the chance that your fears are right.

But - if they are right - then you have a chance to correct them, to apologize, or whatever it takes to make it right again.

All of us say things we are not proud of. The problem with avoidants is that they think they said or did the wrong thing when they really didn't do it.
Questions your intrusive thoughts after an interation and test is you really did or said something unforgiven. Follow this trick: if someone would say the same to me, I would feel bad?

I used to worry for the most strange things. For example, my partner introduced me a friend,,instead of giving him two kisses, I gave him the hand. I felt like something horrible and unfriendly. This tiny thought was with me for days.
