No offence TS, but i can sort of understand your situation here, whereby i can say i'm completely in your shoes(just that i might be slightly better in terms of the experience) but your doubt here won't do you any good be it Physically or Mentally(actually esspecially mentally). What you need to do, is just Ignore it and focus on something else. E.g a Career?And with luck, you might just bump into one. But when that happens, don't let it pass you by

Good luck

I wouldn't say its "Judging a Book by its cover", but i would classify that as "First Impression"
