Recenter yourself in your personal life a bit. That or find like-minded people and make friends with them. If you believe in a cause, then be a part of it, and it may give you purpose. Yes its all daunting and yes we may be doomed, but becoming resigned to this belief is non-materialist; as material conditions deteriorate, things WILL change, for the better or worse TBD. Those around us will never change unless they hear us. Its hard as hell but what else are we going to do?
