Dealing with Intrusive Thoughts about Pet Lizard

When I have these thoughts I just tell myself that they're called intrusive thoughts because.. they're intrusive. They're not thoughts we want to have, these thoughts are often the opposite of what we want to think. So don't feel ashamed. Just distract yourself with something that makes you feel calm (draw, watch your favorite comfort show, take a bath, etc.)

Well normally when my mind is stuck on an image I am displeased with I do one of too things. One, just wait for the image to go away after I stop trying to fight the image out of my head, just let it happen. Two, I try to make my self think of something else I "NEED" to thunk about or think of something I "NEED" to do. It could even be a house chore. But either way it will eventually go away.
