Why do I exist

What is the point I don’t want to be here I contribute nothing to anyone. No one wants me around no one wants to talk to me everyone hates me so what’s the point then. If I don’t want to be here and no one wants me here then why am I still here. Just because people will be upset after I go like I can’t win no one wants me when I’m still here and when I go I’ll only just hurt ppl more why can’t I just not exist.
