I agree with most of what has been said - so I don't have anything to add in that direction...

You have a very generous and giving heart. Not getting appreciated for this can definately consume us.

When I give - I try to do so anonymously - it just somehow feels even better...to be able to give someone joy without them knowing how it was received - sometimes they are even more grateful (of course you will only feel this by watching them and not telling them)
