It does. Especially because being alone... that can be a pain, too. And happiness is always worth trying to surpass that. It's always better to feel good than bad, so that's worth working towards!

Even if you were never meant to know humans... you do now, right? Sure, knowing them must've given you both good and bad things. But isolating yourself too long without friends... I think in those cases it'll be easier for the bad things, the hurt, to be the ones that remain. You have to be able to see your friends and their smiles. That's the easiest way to know happiness is worth fighting for.
