Hii Mudassir

You don't need to get depressed by what has gone by and prepare for what's coming maybe your interest in not in engineering you can start preparing for other college/universities as well as other course preparations . It cleary shows that you have already dropped a year for your jee preparations and dropping another year won't be useful too. Take it to be your fate and maybe you can change your stream and analyse where you interest lies. Decide accordingly

Hope it helps

Thanks
