Hello Sheetal,

I can understand this happens to you as you try to look ahead many questions strikes your mind either which Field to choose and which subjects to choose which will help you and you enjoy doing that . 

For that I will suggest you just one thing just sit back and relax yourself and think which work and study interests you in keep aside the pressure of parents and family beacuse that will hamper your thinking. Just listen to your heart and mind you'll get an answer.

Now a days there are plenty of new options available in India and Outside India which helps you grow in many new fields beside sticking to the same Engineering or other regular courses.

Hope this help you in your thinking. Feel free to ask any other queries. Will be happy to help you.
