hi Ravi
well your condition is no doubt very serious and definitely your academic performance matters a lot after you complete your degree and start with your profession. My true suggestion would be that take AIEEE again. If u can get any of the top 5 NITs then only you should leave DCE (because it is also a good enough college no less than NITs), else try to improve your acad record in DCE itself because its never too late.
ALL THE BEST !!
