I'm not trying to invalidate anyone's experience here, merely adding to what the OP has said themselves. For example, the title of this post, "Do you think you're defying life for no reason" and another one of OP's recent post, "Do you ever feel like your life isn't that bad" speaks volumes about how OP sees their life. And when you read the posts themselves, among other correspondence you have with them, you see they haven't given life a fair chance and they're struggling with self-esteem and perfectionism tendencies among other things.
As for how I know most users haven't faced the same issues I have? Genetic depression only accounts for 30-40% of all depression cases. And even among those, not everyone has those genes expressed right off the bat, which I surely did.

Also, I used to be a life coach; it's in my nature and habit to try and motivate people even if I'm down in the dumps myself. It was not a competition about who has a fairer life but an attempt from my end to empower OP to give life a fair shot.
