I have questioned my self to almost insanity( it wasn't a long trip) about issues like this. I have come to the conclusion- whatever the other person SAW (the action) is up to them; how they INTERPRET it is also up to them- why chew up my insides with WHY I did something- my motivation doesn't matter to someone else if the end result is help when they need it, support or encouragement.

Having depression for a long time I learned to do things not because that I wanted to or was doing it selflessly, but rather because it what I could do at that time!

My questions of motivation go in a journal and just stay there- if i leave them in my head it just messes me up with trying to do the next right thing!
