I'm kind of tossing around these ideas for a PS in my mind now. I realize that without actual statements to read it's obviously a little hard to judge, but which idea sounds more appealing?

1. A little over a year ago I was diagnosed with a disorder that really affects my daily life- makes it hard to get out of the house sometimes, painful, etc (but not anything that is really dangerous). Before I knew what was wrong with me, I was shuffled from doctor to doctor, and since I wrongly assumed I would be cured soon, I applied to a study abroad program during that time. As the date I was supposed to leave approached, I figured there was no way I would be able to go since I was still sick. Then 10 days before I was supposed to leave I got a diagnoses and decided that, even though I was really sick and had no idea how to manage this disorder id been diagnosed with, there was no way I would pass up the opportunity. I went, somewhat blindly trusting that I would be able to figure out how to manage on the fly. For the most part it ended up being a great experience and taught me that if I can handle that, I can pretty much handle anything. In my mind this would highlight tenacity, my optimistic world view, and my drive to make the best out what I've been handed.
I'm also worried this could potentially come off sounding kind of whiny.

2. I'm lesbian and I went to a catholic (and thus oppressive) high school. Didn't realize until I came to college (very liberal one) that it was really okay to be out there. I got involved with GLBT stuff and really realized that I could help make other glbt people's lives better thru my own experience. this is also one of the reasons I am attracted to law. However, I don't have a good "story" to tell about this really (that I can think of) so I feel like this might be too generalized and boring. I'm sure adcomms have heard this story before.

i like the second topic better, but you are right about having to make it your story since it may have been heard before.

but i think the adcomms will have heard more stories about going abroad and dealing with difficulties abroad than the second choice.

AND the second choice makes you look stronger, like you've overcome adversity and been on a meaningful personal journey. that's what they want to see, i think.
