I'm sorry you are feeling the way you do. I don't know much about your story but it appears you are DF'd? Its a shame that policy continues to isolate people from their families....the people that should have the MOST unconditional love for you in the world.
Its not your fault, and even to some degree not theirs. they are captive to a concept. You have awoken with the blue pill,a nd the world is not as you saw it previously. Not easy. Not easy for anyone. There is no magic bullet to fix those feelings. Everyone is different. But think about what you love to do, and do more of it! Make an impact if you feel that is what is missing from your life.
