I have pure-O so I don't have checking behaviors, but I can certainly understand how being in a strange place with a lot of triggers could be anxiety provoking. When you say you aren't going to let anxiety rule your life any more, are you saying it ruled your life last night, but you want to change that for the future? Or did you already get to a place last night where it wasn't ruling your life? You took a big step by staying at someone else's house, I think.
