I've struggled with this too, and one thing I found really helpful was to start keeping a diary--in particular, of the hypothetical situations you're worried about.

I found that after a while, when I would go back and read what I was worrying about, say, a month prior, it seemed so alien and absurd that it helped a lot to put my current worries in perspective.

Best of luck to you.

I came to say this. Write down the things you worry about as honestly you can. The end result is that your worries become more tangible and easier to judge.
