>>6Not a Buddhist or anything but you will need to forgive your family or the betrayal you feel from them will permeate into your life, you will become suspicious and closed off and it will cause you problems. If they have turned against you then there isn't much you can do at this stage, you need to focus on creating a positive situation for yourself and if in the future things change with your family that is good but not necessary.
If you shake off any anger and feelings of persecution from the past you can treat the world as it is: temporary and there to be navigated to find worthwhile experiences from your point of view. There's no need to be offended by your family and their treatment/opinion of you, just as there is no need to be offended when the wind blows off your hat. It takes an extreme effort to reach the point you can see human actions as equal to wind, but you will be much freer if you can manage it.
