Knitter's Block

I seem to be having all sorts of difficulties with knitting lately. First, I decided to get started on my Dad's Re-soleable two-yarn socks but I didn't like how I cast on....it seemed HUGE and I was tired and couldn't put the energy into making my brain figure out the sizing. Then, I knit up a cute Poodle Pink cat ear hat for g-baby #2 but Frogged it due to the fact that unless she has a head the size of the Great Pumpkin (Charlie Brown) then it wasn't going to fit. Sigh. Decided to cast on with smaller needles and realized I didn't own the size I needed. AARGH! Shopping again. Just when I'm trying to Not Spend Any Money right now. Cast on different socks for my son then immediately pulled them off the needles because I just couldn't do it with a needle poking me in the eye. I wish this stupid headache would get lost!
