That's a silly way to think, Hans. Of course they like Medicated You, but Medicated You is just as real a person as Non-medicated You. I'm sure they would like Wide-awake You better than Grumpy And Overtired You as well.
You're ALWAYS being medicated by your body. It's an all chemical all the time orgy in your brain. I don't see anything wrong with exerting a bit of control over the 'festivities', nor does it make it any less you (and if you choose to take the meds, one could argue that it's even MORE you), since it's the you you've built instead of the ones your parents made.
It would be strangely self-serving and odd to write an autobiography at 21. >.>
A
full autobiography, yeah, sure. But that's not the only type - memoirs, travelogues, personal essays, autobiographical short stories or novels, etc. and so on. What we want to read from you is a
memoir or novel or short story or some sort. A great many successful memoirs have been written by fairly young people - the only thing you need is to have finished whatever bit you were writing about. And people are usually keen to read follow ups if add a new addition several years later as well! Seriously, many people make a living off this sort of stuff - I know, because my wife devours it left and right. Most of them get started fairly young, and 21-25 seems about right for initial publishing ages. (And it will probably take you a while to write the book, hah!)
People love reading personal stories and confessionals, and you've got the kind of stories they love reading.
(Hell, with the rise of blogging, the trend in this sort of writing seems to be "tell me about what happened yesterday" rather than fully biographical kind of "tell me what happened to you over the last 40 years" sort of writing)
