"The only thing worse than not knowing if you'll ever be loved is not knowing if you'll ever love."
It may had "scarier" instead of "worse;" it may have said "find someone to love you/to love;" it may have been "the fear you'll never be loved/love." It may have been in the 1st person instead of the 2nd, and it could very well have been split into two sentences. It also could be nothing like any of the options I listed.
If anyone has any ideas, or even thinks they've heard/read this quotation, let me know. It's been bothering me for a while now. Of course with my luck it'll be from a Britney Spears song or something...
Thanks!
