Love, Emotion? or Sickness?

I... have an extremely argueable question. This is for any who have an opinionated question like mine. Love.. a word thrown around from time to time. Is it a human emotion, among hatred, sadness, and happiness? Or a sickness, among flu, diabetes, and cancer? This grand question I have pondered many a night. Yet, I always come to same conclusion, All living things will acquire the best of both worlds when it comes to "Love". It is inevitable, atleast one time in everyones terminal lives will they feel this..thing for someone else. When you think you love someone.. you do. there is no debate on whether you feel it or not, it is there just as life itself. Terminal. You may feel that you would want to "Grow old" Persay with this being. This is a common plea among 2 (or more on some occasions) individuals that "love" each other. Now, don't get me wrong, I'm sure that long before we as a race was created, born, hatched...evolved, whatever you may believe, that we were encouraged to feel this... thing for someone 1 time or another. When you "Fall" for a person.. at first, all is great. You feel..invincible. Like life is as good as it is going to get and nothing can bring you down. Some would call it a Blissful period of time between the begginning and the end. But WHEN it ends..there is no IF, You feel dead inside, weak, useless...Defeated. Now this is a situation at which again one feels can be relinquished with material things or secular ( as Raptor would say) things. This is a temporary fix for a Life Long problem. Some may not ever overcome this feeling.. Hence, Suicide, Homicide,  Maniacal beings, etc. You look at the "neighborhood Lunatic" like something is wrong with them. When in fact, there is something right with them and wrong with you. They have chosen the path to which they will no longer be faced with the repeated factor of life called "Love". They didn't know going into life that this would happen, but when it did, they chose the path that would later benefit them. Yes, they are not "normal" as the regular stereotype would put it, but they have been released from the cycle that would again put them in a state of mind that is deteriorating to human society (somewhat like Buddha's enlightenment). I look to people who commit suicide as not "weak" people, but the strongest people. To be able to understand the hurt of Love to the point of taking ones life to be free from it. COURAGE at its best. Those who overcome it, later remember the memories or remnants of that persons existance in their life. The "emotion" begins to flood back like a wave hitting a shore.. constant, and ever so strong in its path. This is when it begins sicken you. A "sickness" upon which one will chase a relief... material, secular,Religion,science. And so for me and my quizzical brain "Love" is both... and Neither at the same time. How do you feel about this undecisive subject? Love, Emotion..or Sickness? - Skeptical Rodent
