Yeah, i definitely agree with the majority here.. you can't wear it as a bad or a name tag, and define yourself by this characteristic. Its ally our qualities and attributes that make you who you are, this is just a dent in that every now and again (assuming all is medicated and treated well, whatever the case may call for).
As for honesty, well there are some things that you should share right away, some things you shouldnt. This is definitely one of those things that shouldn't come out until later in a relationship. By telling someone really quickly, you are in a sense tossing yourself under the label.
