Checking out is always an option, that will always be there for us. We might be powerless to control every other aspect of our life, but this one thing, NO one, can take that away from us. I think we were given the power of will for this very reason, to choose, whether we want to stay or leave, a decision solely left in our hands to do with as we see fit. Just knowing that we have a way out can provide comfort in amidst the hopelessness of times. Draw the comfort from this knowledge for now. And while we are here, we may as well choose to LIVE for now. Its not like that exit will close up for good leaving us stuck here. It'll always be there.
