same thing has happened to me babe. had one of my girly friends over on friday and persuaded her to have a smoke with me, shes a funny girl so i thought we'd have a laugh, but she had about 2-3 drags and started getting paranoid as f**k then had a whitey so the evening ended up with her a paranoid wreck in the corner not even able to speak and i felt like shit cos i was the one who made her feel like it. anyway moral of the story is your probably better off smoking on your own.
ps i dont think you sound like a bully x x
