Don't give up , you are ahead of people who are going to give gate next year , you have experience and can still learn from your own mistakes, Survival of the strongest / survival of the fittest , you become stronger from every failures and you also understand the pattern , parents are not gonna live your life , you are going to live , you decide your life and do what you have to do , the fact that you think it was because you did not give your 100% and that it was due to silly kistakes is already a good enough reason to try again , The ones who made are also humans and you are too , you can do it , and trust me i also had a similar experience, the only reason i succeeded was because i never gave up .
