Hey bob,
I wish I had words of wisdom (like Theo) but I am in a weird time in my own sitch right now. I know it is hard but if you can recognize what triggers the bad /sad feelings this is a good start. In my sitch one thing I found is that I took too many things personal. I have found that My W is a negative person. She just says allot of negative things. I thought she directed then to me. I in turn would feel bad and I am sure my attitude showed it. Now I just TRY to let it bounce off me and move on. This has left me with a better attitude and I have noticed my W gets back to a better mood.
I don't mean to talk about my sitch on your thread but the point that I was trying to make is that you seen to be headed in the right direction by recognizing the triggers.
Stay strong.
One more thing the Diet Pepsi. OK now we have the FACT & Belief theory going on here.

You have a Fact there was a diet Pepsi in his truck. THAT IS ALL YOU KNOW.

It could have been co workers. I could have been anybody’s he may have been dying of thrust and that's all there was.

The FACT is you don't know.

Belief:
You ASSUME it was hers.

Don’t act on beliefs there is no proof. Don’t let your mind fill in the blanks because 90% of the time it's a negative.

Act on facts.
There was a Pepsi can there THAT"S IT

And if I claim to be a wise man, well
It surely means that I don't know
