Roughly half, maybe a bit more, of my life. But it's not all one continuous missing chunk, it's... bits and pieces throughout. I think I have most of the important events back, that I know of, but most of the littler details, the in-between things... The details I do have are a bit... messy, too.

I know my birthday, but not my age. I know my parents' jobs and personalities, but not their names. I know my best friends, and how we met, but not how we got through some of the... worse events. I know my name, but that's useless, since I use a different one now.
