Don't hear to those who are so demotivating for you. You are always full of probabilities. If you can't crack NEET/EAMCET this time try to do next or try to do anything else if you are interested in it.

Failing an exam doesn't mean that you are a failure. So don't bother with such people. You should follow up and prove yourself.

I hope my answer helps. All the very best for your future endeavors!
