I can see that all these issues might have been making it really difficult for you to relax and focus in your studies. But I am just wondering, have you tried conveying to your parents how their words and/or actions are impacting you and making you feel? Many a times the way our parents try to push us to work hard kind of makes the journey even more harder, which in turn, makes us feel more distant. But that's not because they don't love us, but might be because they think it will work. And therefore it becomes our duty too, to make them see that it is not helping and is only making things worse for you. Try to explain them how you want to be supported. And see if that helps or not..
