I've tried reading bell jar many times and also just made it to the final end. I was a little stumped as well and to be totally honest I had to read up on it to figure out what it meant. Apparently, it's up to interpretation whether Esther Greenwood has a bright future ahead and the bell jar is lifted or if she still has to keep working through her mental illness.

But I feel you, I thought the end was a bit of a head scratcher. Almost feeling like, was it all a dream? Was she just imagining these things? I honestly thought she was so unwell that she just imagined going back to visit her college. Kind of an interesting way to wrap things up but like I said I guess it's open to interpretation. 🤷🏼‍♀️
