Yet, it's almost impossible not to be pulled down & into one's own small life at times - to take one's own burdens personally - this is especially true for people suffering from depression. Adding street drugs to the mix is deadly.
BUT, regardless of how challenging life is, there are many who face it bravely, intelligently, with relentless will & energy. Perseverance & an open mind-hearted embrace of all that is.
Never ever give up! Seize the precious chance to evolve till the very last second of your natural life.
