ask your teacher to talk to them about this matter or your college principal
show them your potential and give them examples of others ...so that they can able to understand you ..
I also try this but they didn't understand they ask me you have only 2 options 1(parents)2(study)so what should I do in this situation I think to do suicide but I like psychology so I did not do suicide
tell them that you're studying just because of them to make them happy
tell them that you wanted to suicide but you're doing this just for them
