I do not know how many people may experience this so it will be helpful if I can get some feedback.

Now there are times when I will do something for someone thinking that I am doing it for one reason. But afterwords I realize that I may have done it out of a much more selfish reasons.

I figure it could be several things. It's possible that I just loathe myself so much that I do not want to allow myself to feel good about helping others out.

It's possible that I just over analyze everything and given my pessimistic nature see the possible bad easier than the good.

I may actually do things that appear to be out of kindness but am actually using the opportunity to manipulate the emotions of the other person.

Granted for the most part I do actually help people. I find that when something mutually benefits both parties that life is generally easier. Of course there are times where I seem to end up ahead even if things do not work according to plan.

Does anyone else ever experience things like this where they are unsure whether they can trust their own reasoning behind a given situation?
