You are not alone in feeling this way. Unfortunately it's a weird world that we live in where we are conditioned to believe we owe something to people if they did/gave something to/for us out of the goodness of their hearts.

I am constantly encouraging people to help others, not because "it's the right thing to do" but instead do it for selfish reasons.... Because "it feels great to help people". ;)

So although you might think it is a burden on them, it may actually make their day because it sure feels great to be needed!
