Amy I felt the exact same way before my surgery same reason...did exactly the same thing went to a fair went to the movies... sat around a camp fire and just had some laughs...I understand how difficult it can be ...If you are anything like me you over analyse and think constantly but you know yourself best..do what works to keep your mind occupied...Laughter does help..and for me was writing journaling and talking to people here who are supportive..If you need to talk there always seems to be someone here...
