guardian angel?

Was watching a show called guardian angel. It is a programme which based on true account of people when they are down and lonely, someone is there to accompany them, encourage them.. After i finished watching the 6 episodes, I realised that the guardian angel beside them was mostly their parents.. be it is their mother or father.. Somehow it reminded me on how 'badly' my mom had treated me the past few years and even now.. She keep doing things that hurt me and when I needed someone to be there for me, she wasn't around or she was ard but doesn't care.. I really envy people who can communicate with their parents and in a good relation with their parents because I dont have such family.. I have been contributing to the family silently without anyone noticing it.. Actually i dont mind contributing silently, I just want my mom to encourage me whenever i need it.. but guess is just a wishful thinking of mine..The knot between me and her would never be untied.
