How to forget pain from family hurt?

It is difficult to get over being hurt by your family or for your family to get over being hurt by family.

In this world we are pretty much alone unless we are fortunate to have family or a few good friends so when family hurts you this feels unbearable if you were a close and good unit.

However "Time heals all wounds" and this also will pass.

"Forgive and Forget" otherwise you will prolong the sadness.

It's very very hard. Family are the people who are supposed to love you. I know that it took most of my lifetime for me to forgive my father for being an abusive drunk. But my life became much happier when I was able to forgive. I was able to remember good things about my childhood and my father. And yes, he was a drunk and he abused me, but there were good things about the man, too. You really do need to forgive. I discovered that holding bitterness and unforgiveness like that really hold you back and block you from being genuinely happy.

I don't think you ever forget about the hurt, but you can put it in the back of your mind and not let it rule your life anymore.  Don't talk about it to anyone; don't think about it; and for goodness sake don't dwell on it day in and day out.  If you do that, the hurt will stay with you forever.  You really do have to forget it and move on with your life.

Try to see a counselor or therapist if you need to talk it out, or get a notebook and write your thoughts and harsh feelings down.  You can keep the notebook or burn it, but the feelings and thoughts will have been sifted out of you and onto the paper. That will help.   Forgiveness is the next big step, but to completely forgive, is often completely impossible for those who have been deeply hurt.
