emotional reactions

Have all y'all ever wanted to live an emotionless life? For as high as I can occasionally get, each moment is dampened with the fear that there is a low just around the corner waiting for me to unknowingly and unsuspectingly venture through the doorway. Actually, I guess I neither unknowingly nor unsuspectingly venture through the doorway if I know what's awaiting my arrival, now do I? If that's the case, why bother going through the door at all? Is that what drives people to commit suicide? Are they just cowards, unable to embrace their fate? Are they merely avoiding the inevitable chain linking the experiences and feelings that create their existence in the first place? Is that all life is made of? Circumstance, emotion, and reaction?
