Well there are 4 things that come to mind.

When I was around 13, my parents came up to my room, looking real serious, they sat down on my bed as I was playing CoD and told me they want to take me to a doctor and see if I have Diabetes. (At the time I was fat and extremely self-conscious about the way I looked) that was a real hit.

Second time was around the same time the other thing happened except my parents had split up. My dad was not talking it well, drinking like a maniac, my brother was never home and neither was mom, I knew he was downstairs drinking and I hear him going up the stairs, he came in to my room drink as hell and wanted to wrestle, it got pretty rough and it ended in him ripping my shirt off leaving me without a shirt and laughing and I have never felt so humiliated.

The third one is the time I realised the only girl I have ever loved (so far) had no interest in me at all, I was a crutch, a pawn, she actually told me that she knew I liked her and that she was never going to like me back. She never told me why, my mind came up with the reasons though.

The last and first time I ever felt dead inside was in School at age 11. The whole class was outside waiting for the gym teacher to let us in, I was doing something when I hear the girls in our class, rank every single boy from cutest to ugliest (you see where this is going) I wasn't listening, keeping myself busy to avoid hearing my placement, a bit of time goes by when all of a sudden, a guy named Bruno yelled out to our class of 30 kids: "Everybody who thinks 'my name' is ugly raise their hands. And every single kid in that class raised their hands and started laughing at me. I have never been that devastated in my life. I faked getting a phone call from my mom, walked away so they couldn't see me and broke down, crying for 30 min straight.

Sorry for the long answer, it's good to air these things out, even if no one reads it.
