Uphill battle

I've been struggling to climb out of this pit for the last two days, and I think I'm finally getting somewhere. I was actually a little bit productive today, and I'm starting to feel excited about starting my experiment next week instead of just feeling scared.

I feel that I should try to do some light-hearted fannish stuff to improve my mood, but the fannish part of my brain wants to rekindle my love for Les Miserables, which is not the best option for that sort of thing. Any suggestions?
