Should I read sad books, such as The Bell Jar even though I am suffering from depression myself? ?

I really want to read The Bell Jar by Sylvia Plath. I know it's a sad book about deppression, I feel that it may be good has I can relate to the story as I'm suffering from deppression myself although I'm recovering! It sounds a bit hard going though, I'm not sure if it's a good idea or not??
