What do you do when the obsession could turn dangerous?

The new thought that keeps popping in my head could turn into a trigger for me so I am trying not to think about but it but it keeps popping back into my head. It's like telling myself not to think of a pink elephant ya know.

I have emailed my T and told her what is going on but she has family here this weekend and I'm not sure if she will be checking her email. I am not in danger or anything it just annoying and was wondering what do you do if the thought is bad?
