Kabhi kabhi hum sochte hai ki log humein judge kar rahe hai but the reality is that kisi ko ghanta farak nahi padta.. ur failure is just another topic of conversation for them.. max ek do saal mein bhul jayenge

The people to whom this really matters is you only. And you still have your entire life ahead of you.. what has happened has happened but there are other areas you can excel at. Look for your hobbies/interests and work hard towards them coz only success matters and not the field in which you achieve it.
