I didn't read every post but I'd say my reason is similar to the OP's. I suffer from Depression and often times feel small and insignificant. But, Lalas are small, but far from insignificant. We can do everything, be anything, and that makes me feel like I have a chance.

Real life isn't easy for most people, and it can be harder when you suffer from Depression, but in this game I can help people, I can actually do good, and make money; that's really hard in real life. But I have friends, I have people who want to spend time with me. Most people don't know how a game like this can help so much.

And, while I might have gotten away from the Lala reason, being a Lala is how I truely see myself. Not only because of the empowerment, but I am hella cute. I get comment, pats, hugs, you name it. I'm even told that I am one of the cuter lalas out there because of my general look but keen glamour sense, XD.
