Looking for a cite for a Sartre quote

[ndorward]

Copyediting an essay here & the author inserts a quotation from Sartre:

As Sartre says, “I await myself in the future, where I make an appointment with myself on the other side of that hour, of that day, or of that month. Anguish is the fear of not finding myself at that appointment, of no longer even wishing to be there.”

& I need to look it up (& get the page number & check it for accuracy). I gather it’s from Being & Nothingness, a doorstop-sized book, so I thought that before I actually start flipping through it doggedly maybe there’d be someone here who knows what page of the book it’s on?

According to this fellow, the quote is in a book by D.D. Palmer on Kierkegaard.
