Edda, I have the same thing happening at times ... where I get triggered myself when trying to reply or the words disappear even though I know what it is I want to say. Sometimes it takes me several attempts at writing before I can press the post reply with times of leaving the post between each attempt and other times I have to just step away from it (and as others have said the thanks and hugs button can be helpful then). Not sure about ways to get over it exactly; but maybe noticing what it is that is triggering us about the posts and continuing our own work on those areas can help over time
