I read the Bell Jar when I was about 23 and it resonated with me so much. If you haven't given it a go, I'd recommend it!

I found it relatable and reassuring to know that I wasn't the only one to feel a bit unfocused, untethered and worried a misstep might throw off the trajectory of my life. I can't say it resolved everything for me, but I guess I felt less alone in the struggle.
