I see a lot of good information and ideas have already been presented, but for everyone who views this thread I just wanna further hit a particular idea home: do what you feel is best. This site is all about having fun. If you aren't having fun then what's the point? If you want to portray a particular character or hit particular themes there is nothing stopping you (provided it isn't overly graphic, due to site standards and all). All of you are here to enjoy yourselves but you aren't responsible for the fun of everyone else. Everyone has personal tastes and ideas that they cater to, you don't have to cater to any that aren't yours.

Want a character with clinical depression? Go for it. Want to improve as a writer and make it as accurate as possible and do research? Go for it. Want to just have fun and run on intuition for how this character would think and behave? Go for it.

This applies to all "sensitive" topics. Fiction is separate from reality so you shouldn't worry yourselves about whether you are living up to other people's standards on a site that ultimately is for your own fun. Decide your own standards and then live up to those.
