Would've, Could've, Should've

(Definitely NOT would of, could of or should of.)

Should I be annoyed when I tell my mom how annoyed I have been the last couple of days and she replies by saying, “Oh, well; that’s life”?

Should I be aggravated when, for some unknown reason, I am unable to get the link for the recent Lotto numbers to work?

Should I be hopeful? Optimistic? Upbeat? And if so: Why?
