obsessing

I have less than a week now before I set off. I am obsessing The kit is all out on the floor. I keep going through it looking at what can be left out and (so-far successfully) overcoming temptations to add more. I am spending endless time on this forum reading posts (and thank you, there is such a wealth of helpful and supportive insight here). I have a very long list of final jobs that gets longer rather then shorter. I am practicing Spanish (still poco). I keep looking at the airline website to check I haven't forgotten something that will cost an arm and a leg. I have started a blog. I have twisted my ankle and spend time contemplating the lovely yellow and purple colours. Half of me is so excited that I walk around with a permanent inane grin. The other half is scared witless.

Is this normal behaviour?
