I get asked that a lot when I'm at the peak of my self-loathing and I never got it. It's not the same. The damage isn't personal. You don't hate your friend.
Let me counter that with another question. If that friend failed a year in school and was held back, so now they hate themselves for it, but somehow that is directly the cause of the same thing happening to you too, out of no fault of your own, the same damage was applied to you too, would you really be so merciful and kind then? Would you really just let it all go and comfort them anyway? If so, then you're a far better person than me honestly. I'm bitter and when I'm hurt that badly, I can't just "let it go". At best, I'd just cut contact but I can't really do that with myself now can I. I'm just stuck with myself forever.
