The bell Jar

I've read to chapter 4 in "The Bell Jar" it's an okay book but it seems like it's going to be very sad. I can tell that she has self-esteem problems and she's very self conscious. She doesn't think she pretty. I also like how she writes as someone who she thinks is pretty.The book also in a way reminds me of the movie a girl interrupted. I can't wait to read farther into the book.
