I really recommend it 'whyshouldilive'. Yes i have her collected poetry, my favourite poem of hers is 'daddy' its very angry and moving at the same time, i also have a collected works of short stories called 'johnny panic and the diary of dreams' i think, i say that because i have yet to read it and may be getting the title wrong as i'm in a confused state at the moment. I recomend her poetry though, the pictures she paints with words are beautiful.
I also like Prozac nation by Elizabeth Wurtzel, i find alot of similarities with that and the bell jar, i also read 'more, now, again' which is about her strugle with drug addiction, its kind of a follow up to prozac nation, i got that book signed by Elizabeth herself which is kinda cool. Really sad that the movie of Prozac nation has been shelved, was really looking forward to seeing that, Christina Ricci was playing Elizabeth, would of been a great movie i think, hoping that maybe they'll release it later x
