I would think that your emotions are first intruding on your thinking capacity; so
you have to make sure the thinking is clean to start the process. By "clean" I mean
that you have nothing in your past that would drive your emotions to be suspicious
in coming to a clear perception of reality.

Integrity always leads to a clear perception of reality, I think. Tell me if I'm wrong,
but I've found it to be true many times.

If there is something in the past that causes you to be overly suspicious, please get rid of that by talking about it with your psychiatrist. That's a major benefit of therapy, I think--to get rid of distressing past events that intrude on present-day thinking. We must forgive others or ourselves of those things first, IMHO.
