I'm with Psyched on that. There's no need for 'transparency' when you're just starting out, getting to know people. If you're not comfortable with it, then there's no need to worry about it.

I found that when I was first classed as 'disabled', I didn't know how to tell people either. I started to focus on my hobbies and after a while, when someone asked me what I did for a living, I'd tell them that I'm an artist. If they asked for more information, I just said I was working on 'expanding my portfolio' and left it there.
