Glad to hear you sound better Leo! Doing something for yourself, to make yourself feel better will help (although none of the things apeal to me personally but I'm not you so it doesn't have to).
I was never this bland before I got ill. I used to wear pokemon socks (great in a public library I worked in then with kids), bright coloured shirts with Sailor Moon or Miffy on it. I never died my hair though. No tattoos or piercings, my body react anything "alien" (which is embarrassing when it's stitches) so that would be a bad idea.
Neither am I. I really dislike tattoos and excessive piercings. my wife is planning on getting some part of her ears pierced soon. Not sure exactly what part, but that's okay.
