I have a kid (6yo), I have definitely found a lot of my happiness in being her father, but I see it as a giant responsibility first.
Like, it is amazing, and I see I get, as you'd say a lot of benefits, but the lens you view it seems weirdly side-ways.
Counter point, the fewer loving relationship and purpose you have in life, the harder is to raise your child, the more loving relationships and purpose you have in life, the easier and more rewarding it can be.
(Counter-counter point, yes, you can have many loving relationships and great purpose and goals in life that would be anathema to raising a child)
I'd say, go talk to your friends that already are parents? This seems to be one of those conversations that deserve full attention of a in-person conversation.
