Why is this?

This is a pretty useless post and I'm just going to vent and that's it.<br><br>I have no plans of starting a family or having kids anytime soon. And I'm actually quite firm on that particular decision. I'm 22 years old and I already know that I want to spend this life alone. Because of this, I don't even know why I'm allowed to exist. It's useless to have me and I'm useless to everyone else. My parents should've just never had me and just had my siblings alone. Why did I even need to be here in the first place? What's the point? I'm not doing anyone any good and I definitely don't do anyone harm. I just exist uselesslessly. And I hate that feeling of uselessness more than anything else.
