One small thing goes wrong and then you question everything in your life - it is a small thing and well it could have been worse but then you cannot get it out of your head. You ruined something which was not yours to be ruined and you feel bad about it- very bad about it. That should not have happened, and not all you can think about is that. That is frankly annoying and now you are questioning the decisions that you have made for yourself for the coming weeks. Then you think about the possibility of what if something goes wrong. Then there would be no coming back from that, and that is the worst thing that you can imagine. Now there is a fear in your mind about all the things that can go wrong - and you are going around in circles thinking all the things that could go wrong. Which is frankly annoying the shit out of you. You need to sleep. SLEEP ! SLEEP! SLEEP! SLEEP!
