I can sometimes too be an addictive personality especially when finding something new that interests me, then I'm consumed with it to distraction of everything else going on around me.

I used to be a highly co-dependant person and couldn't be without another in my life, ever! Now, I'm happy to say it's been a year and a half that I've been on my own without having to desperately cling to another and I'm finding it quite liberating and highly enjoyable hehe (I don't know if having my daughter counts as being co-dependent or not but I don't think so )

I am a smoker, not heavily (4 or 5 a day) but still quite addicted but that I don't think is anything to do with being sub, just a terrible habit lol
