There is a beauty - a terrible beauty in sadness. Sadness is a feeling, an emotion like any other but when it becomes our only or our prevalent emotion then we maybe need to start delving into the Whys and you did that very eloquently in the second stanza. Self reliance is a fine trait but again when it becomes the overwhelming trait in our dealings with the world it can become a negative. The final line is a true glimmer - a real gem of insight in a write full of self-exploration.
Well penned Ariana. :)
