How then do I mange the expectation of people on me such that i don't get into depression when I'm unable to meet up with it.?.
Simple: don't meet their expectations. Are you a people-pleaser? A people-pleaser will do anything that other people expect you to do, or you will make decisions or movements based on what other people expect from you; if not, then why bother about the expectations of other people? In this current world, you should become independent, meaning you should mind your own business and ignore what other people will say about you. Don't let what they say about you go through you, because if yes, then it will only limit you to what other people expect from you. What I mean is, if you want to become an artist but other people or your parents expect you to become a doctor, will you follow them? If yes, then you are limiting yourself to what other people want you to be; you are exchanging what you want for what other people expect from you. Don't please anyone because you will be the only one affected.
