Do it. I'm not a strong person but I did it. It felt crazily dramatic. It felt like I was being ludicrously self-dramatic. Hard to explain. I think it's because you put up with shit day after day so you think 'why today?'' why react today? why react to this shit?! so you're not thinking god, years and years and years of this. You're thinking but I put up with this shit yesterday and the day before so why today and why this shit.

Well, now, if somebody pointed to a stranger in the distance and said that stranger thinks you're selfish, you're impetuous, you're chaotic, dramatic, hysterical, you're needy, you're never satisfied, blah blah blah, I@d just shrug. THAT is the same way I feel now about my x's low opinion of me. What he thinks of me is none of my business.
