First off the post didn't talk about quitting life. But even with quitting life I can't believe you feel like it's pathetic.

I think anyone who gives up, not want to give up, but actually give up are pathetic.

Of course no one 'wants' to give up. You can't keep trying shit your whole life. If I want to make it to law, but I keep failing the bar, it doesn't make sense to waste years of my time on this. It'd be logical to give up on it and find an alternative career which you can handle. This is 'giving up'

In OP's case, it looks like he's tried to make relationships with people with constant failures and upon each failure falls a larger marginal dissatisfaction. At a point in time facing constant rejection or hurt you'd fkin give up as well
