Help!

A belief or theory or whatever saying that human beings are social animals is stuck inside me. I feel awful many times when someone asks me to help, but they don't show any respect on my advice. What I was trying to say was "Why do you need me to help despite not believing or trusting what I've given an advice?" This kind of thought strikes me and I am so sick of helping somebody like this. You just need me to lend a hand, why don't you turn a wall toward me back? How can I escape from this idea? ??? or just saying that I don't know, or I just never say a word. That would be worse though. This sort of conflicts is waiting to explode when I can no longer put up with.
