Absent-minded

Definition: Deep in thought and heedless of present circumstances or activities; preoccupied

I always thought I'm absent-minded but after looking up this definition, it can't be me right? Because even though I'm always heedless of present circumstances or activities, I've no idea what I can possibly be deep in thought in or what I am preoccupied with. Going along with that, perhaps I'm just blur-minded - mind that is vague and indistinct, hazy and fuzzy.

Evidence:
#1 On Saturday, I tried clearing customs with a passport of less than 6 months of validity.
#2 Earlier, I stuck my hand in a jar of milo powder and wondered why the biscuits were so powdery.
#3 This morning, I got on some bus and thought it was the bus that goes to the office, only to have it turn left instead of right as it should.

I would like to kill myself. Would you like to kill me?
