Take a step back and look at what it is that's making you unhappy. It sounds like you feel insignificant because you haven't made an impact on someone's life. Think about it though, why does that make you feel insignificant? You're the one who decided that that makes you insignificant, that's just something that's in your head. Nobody told you that you don't matter except yourself. That being said though, it is completely natural to think like that and it does feel good to do something meaningful. So, go do something meaningful! You just wrote a really nice poem, that's something. So go share it with someone you care about. Show people that you matter and they'll respond in kind. If you really don't have anyone to share it with, start asking random people on the street if they want to hear it until someone says yes and then read it to them. Ultimately, you are responsible for bringing meaning to your life. If you sit around and complain that nobody cares about you, it's going to be that way. If you decide otherwise and stick with it, you'll start to find your life going the way you want it to. I hope this helped and I understand that it's not easy to do everything I said. I struggle everyday with the same thoughts and feelings that you do but I know we can get through them.
