I want a baby

Here's the thing. I'm 17 and I want a kid. I know deep down it is not the right thing to do and I know I won't have one for many years yet. But I just feel I have no purpose. And the only thing I think could help is a baby. I know it sounds silly. My partner and I have been together a year now. It's still fresh I know. But I don't know. I want to be more.
