I think you are the most calm person in the group.Fella! you should sleep well otherwise you will have to see a psychiatrist even before you send your passport for your COPR . Submitting your application is like doing a bank Fixed deposit , you should forget it after you do it . My only question is why are you stressed if you have submitted a complete application ? They don't judge you by your name or country of residence or other factors whatsoever unless there is a problem with your application. Even if there is a problem with your application ,they will seek clarification unless you did a major blunder like not submitting your PCC , medicals or reference letter. SO SIT BACK , RELAX and GET A LIFE.
Cheers!
Please keep it up!
