If you want something that you can do also alone, while you are looking for another therapist, I tell you what I usually do with my intrusive thoughts: ignoring them. I mean to try to relax and to say: this is only an obsessive though, it's not happening in real life. Or something similar. It's difficult, I know, but it becomes easier after some time. You could try.
Maybe you already tried...but I hope that this helps however.
Good luck
