I can't imagine the pain of being separated from my daughter. You will be in my prayers man. Depression and addiction is no joke and many people honestly struggle with it. To reconnect with your sons will be a very joy filled day I bet.

I know you will do well to walk with your sons and show them the light. You past problems will make you much stronger and God will use that to bless others. take care of yourself brother. I'm here if you need to talk or anything.
