I just saw ur profile .. u r still in 12th only .. so u have a year more with u .. isn;t ?
So, there is nothing to get so much worried ..
Yaar let me tell u .. i have never been in this situation .. i cleared JEE when i was in my class12th ... but i very well understand .. how it feels ... but yaar see, my mother always says .. u cannot always win .. u have to lose and failures are just part of life .. wat is important for us is that we work and rest is just wat god wants ..
Even now when I have moved into IIT and now I am almost in my last year .. there are times when I get really depressed by failures .. winning has become a habit ... but then I talk to some of my close frnds .. my mother .. they help me out .. let me tell the people u believe in like I d oin my frnds and parents .. when u hear them say that "IT IS OKAY" .. it does magic .. u feel that yes the problem is not big ... and it is just a phase and will pass by ...
Yaar, one thing is that u still have one more year .. other thing .. wat happened has already happened, there is nothing more that u can do about it .. if u will keep thinking about it , then it will only harm u and do nothing good to you ... one of the immediate consequence will be that u will do badly in your AIEEE etc. exams ..
See, do not think JEE as something really big ... it is just a exam and the IITs just some institutes .. it is true that IITs are gr8 place , but that does not mean that other institutes are just useless .. I am talking on basis of some real stats .. and according to those I can claim that there is not much difference in the type of companies that appear on different institutes and the people at top .. watever college they are in ... get similar jobs ..
So, dear , just realx ... things will become okay ..
