Do you have to be useful? Figure out how to be happy, and be a good person, a good happy version of you first, then you will naturally be useful to the people closest to you, and to yourself, and that is a very good thing. So much of society pushes us to be "useful", and in fact we are (most of us) dutifully join the march through the education system and into the workforce, allowing the system to fill us with information that it deems useful for its own perpetuation. So you are already playing a "useful part" from the point of the system in which you came up. Given that, sounds like you are really more asking about "significance". How can you do something "significant". What is significant for you? That's what matters. There's always millions of super critical and significant problems in the world that you could solve: only matters is what ones do you care about yourself. If you don't care about it, you probably cannot really have an impact in significant way. So I guess you have to maybe find out what you really care about first. Then the answer may seem natural to you about what to do. How can you find this? I guess, get more life experience and try many things, and reflect on your experiences, thoughts and feelings to know yourself better, and to know the world better: then you can make better choices for you in it. :) But if just not overthink, disconnect from your own mental and emotional drama. Do meditation and yoga. Let your life be happy. Watch some Sadhguru videos on youtube. You can probably not figure things out when your mind is racing in this kind of way.
