As a real book worm, I knew that this book was semi-autobiographical before I read it, and I had thought that Plath would struggle to remove herself enough from her situation in order to be able to write about it in a subjective way. I am pleased to say however, that I was mistaken! Plath describes excellently the plunging depths of depressive illness, even conveying to me - someone who has never suffered from depression - the true despair and suffocation that can be experienced.
The bell-jar itself is a description of how it feels to fall into a period of depression- entering into a suffocating, surreal and distorted world where only you live- unable to communicate with anybody.
One piece of symbolism I really enjoyed in the book was the notion of the fig tree, and how your life can be represented by a fig tree...so many branches representing the many paths you could take in life. The choice of; which branch will lead you to a delicious fig?...but the ever conscious notion that if you take too long to decide your path, the figs will all be rotten by the time you pick one.
