Feeling Bad at Slips of the Tongue

I don't want to repeat them.  One thing I said was stupid, like, "that stupid pen" except about people.  I was being treated differently for what I post online like people can tell.  So, I thought maybe using things like that in the right way if wanted to be used.  I said it watching the movie and with my dad.  I was mad and said other things.  I wish I could redo my life.
