No idea what kind of parent I would ever be

I'm broke, I can't exactly provide stability financially, emotionally and I have issues with substances I won't name at the moment. My nieces call me their #1 uncle and honestly I'd move heaven and earth for those two. I'm also the godfather of my bestfriends kid too. I'll probably never have children of my own someday and maybe it's for the best. Maybe I'm just destined to be the cool uncle who is a believer in 711 snack runs and getting far too competitive in mario party.
