Okay. Haiti was just an example. There's lots of people you can help close by. There are Christian organizations and interfaith groups working to help those less fortunate all over the place. Locally is just as good.
Or you could simply join a support group and learn to help others through their pain while healing your own. Specifically, you can talk to other alienated fathers and victims of D and share your story and your experiences.
You could take it even further by joining a shared parenting political advocacy group -- or starting one. Lots of fathers have been screwed over by our justice system as you have, and many of them and their (current) W's have become alarmed enough at these injustices to try to organize and seek remedies.
All are suggestions. But the thing you need most to do is take the first step, as others have also advised. Baby steps then. Baby steps. But keep moving forward.
