From this list, I'll go with What If? because you don't have to commit to whole book, you can just read a chapter or two and switch to another book if it doesn't suit your mood, or "scifi romance Aurora Blazing by Jessie Mihalik", seems like a lighter read then others and I find lighter reads easier to get when in a funk like this.

Of course, that's just me. Good luck with whatever you choose!
