Oh dear, I'm so sorry this happened to you. It's happened to me also so I very much understand your feelings.
You also sound a lot like me-- I would give the shirt off my back if it would help someone else. I have done things like that even.
I hurts so much to be misunderstood-- but like others have said and which I'm trying to do also-- is to truly know that you meant well and try very hard to ignore the hurtful responses.
Sometimes we can't make things right

-- so then the right thing to do is to move on.(IMO) as hard as that may be.
jlove--

my heart is with you.
