i do that sometimes, hit myself and forget i did it and wondered where the bruise came from
only got 4 hours sleep last night then was up all morning thinking about things that have changed me for the worse like my fiance passing away and other things
then instead of complaining you should do it
i just woke up from a 30 min nap then lunch and shower
now i have nothing to do but might go outside and see what dad is doing
