Have you ever examined where your trust issues may be coming from? Sometimes we need to go back to the root to discover the problem. I also have racing and obsessive thoughts which are hard to deal with. When things are bothering me, it isn't until I get down to the very root of them until they leave me alone. Sometimes that's not always possible, though.

For example, I used to worry compulsivly about the bullies who had bullied me in high school even years after it was over. It wasn't an issue I could resolve because those people were not in my life. I couldn't go back in time to repair things. I had to work very hard to resolve the issue within myself without ever being able to confront those people. It wasn't easy.

Trust issues can destroy relationships, though. Have you tried taking your wife to the therapist with you?
