I liked all of yours..

I'd have to agree with not knowing..

if I'm going to get any sleep
if I'm going to get up once I do get some sleep

and I'll add not knowing...

what medication is going to work and for how long
whether my good times mean bad times are inevitable
if all my best qualities are just a pathology
what the heck to do with myself / my time
if I'm going to finish any of these projects
if I'll be able to keep my big mouth and my wallet shut
if I'm going to spend the rest of my life spinning my wheels
if I'm going to pass this on to the best thing I ever helped create in my life, my child
