Honestly, if I'm sick of thinking about something, I just make the conscious decision not to.
Why should you subject yourself to that? Allow yourself to breathe and entertain some new, positive thoughts.
It's not easy at first and you do have to force it a bit- but it's not impossible.
Conversely, you can just think about the thoughts continuously until they hold no real power over your emotions.3

Just simply don't think about them. I've never thought of some bad memories for like 10 years and I can't recall them ever if I strained myself trying.1
