I am feeling anxious/ unsure about tomorrow

basically, I've ended up with two coppies of a dvd and want to sell one. in order to do that, I need to go in to town and register at the store which means I need to talk to a stranger

the horror... I may not go, and just keep both copies

plus: I've not done very well today in terms of being present (abuse memories), Sso I don't know if it is the best idea..
