My Friend, I don't know you other than what you wrote, but haven come down a simular path of believing and then having lots of major doubts about the church, I certianly hope you would reconsider your position.. To have your church records pulled is a Major step and one that could leave you lost. Please consider a period of inactivity first while you think about and consider your options. Being inactive was one of the better things I could have done for myself..
As to how your family is treating you, they are in pain like you are, maybe even more so at your decision. While this does not make it right nessissary, it is human nature to pull away from things that causes pain. My family didn't support me when I converted the first time, and they still are not "happy" about the things that I've done. However, after enuff time I seem to have worn them down..... But it still hurts them.......
Peace to you my brother now and always!!
