I am going crazy nowadays I am insecure.

I can understand what you are going through and it is not easy to handle the issues. But that doesn't mean you have to live with problems.  List out all the challenges that you are facing (your academics,  passion, level of confidence,  relationship with your parents, your relationship with boyfriend etc). Prioritise which is most urgent and important to resolve and work on that, followed by next item in your list.  First you might have to strengthen your bonding with parents,  win their trust and concern,  address your passion and academics and convince them what you want to do in life. Maybe you can consult a Career Counsellor for help.  Accomplish one thing at a time and strike off. Keep the boyfriend issue on the back burner as of now. That will sabotage all other challenges you have on hand. Seek help from a Counsellor in your city who can help you to systematically approach and manage/solve the issues.
