I also have acne, and given a choice I would choose NOT to have it.....
But as far as things I hate about myself go, I have to choose my lack of interest in ANYTHING.

For the past.....ohhhh.....seven or eight years, I've had it drilled into my head by every adult I had ever talked to, that I MUST choose a career path, all I had to do is think about what interests me, and there will be a multitude of directions to go. Then I asked them, "What if nothing interests me?", and every one of them responded, "Everyone is intereted in something."

Well, as it turns out I am NOT interested in ANYTHING, and since no one belived I was telling the truth, no one helped me. When I got to college, I took a "Career Decision Making" class, where I took a career apptitude test, which was supposed to tell me all the career paths that might interest me. My test told me that I would not be interested in any career.

Needless to say, I failed that class.

"Lack of interest" is listed under the symptoms of depression, so maybe this is all just a figment of my imagination, but I long ago came to the conclusion that I would end up with a low paying job that I hate. This, incedently, is NOT the best way to plan for the future, and as a result I had no ambition to do well in school, and no desire to get an education.

Anyway, the main point of this is:
"One of the things I hate about myself is that I have no interest or ambition."
Sorry it took so long for me to say it.
