You're lost in a tunnel full of depression. Depression maybe illusion to many, but it is actually you being suffocated when everybody else around you, seems to breathe in a perfectly fine manner. This tunnel is actually not an itinerary. It is something that everybody has to travel, not today, not tomorrow, but definitely some day. You leave your (current) destination, travel the whole journey, just to arrive at another destination. The journey feels like a perpetual one, and you don't even know about its ending, no ball park figure is ever given. But then out of the blue, a ray of hope is visioned, an omen that it's gonna be okay, it's gonna end.
People reach at two (different) destinations.
We all know about those two destinations. It's either exhilarating or excruciating. It all depends upon you, you're the one who has to decide which of the two you've to choose. Even if you choose the wrong one (as you think), you can always change your mind and implement upon it for a hard yet a satisfied change.
We have infinite options and chances in life. Even when we're wrong, life gives us countless chances to make amends, albeit we don't (usually) deserve those chances. All we have to do is to try. The tunnel is just an option, if we see. You even have the option to enjoy your journey and make it a happy itinerary. Instead of moaning, whining and grumbling over all the negativities, we can choose the option of staying happy, all the time!
All I can say is, much of our pain is self-chosen.
