The other thing that botheres me about this surgery, is that it's not addressing the problems in the person life that are causing the depression. All it's doing is eliminating the emotion that goes along with it.
In my opinion, based on my expierences with depression (I'm sure it's different for everyone so this isn't absolute), there are things in a individuals life that are causing them to be sad. Some of these reasons may be deeply personal, and the person dealing with it, might not even be confortable talking to family about it (family can even BE the problem sometimes). For fear of their reaction. They also might be afraid of how others would look upon them if they eliminated whatever it is thats causing their depression. Fear of disapointment. The whole, if I did this, I would be being selfish, for not taking into consideration other people's feelings. Etc etc etc. But sometimes you just gotta say, f it, and do what makes YOU happy. Are people gonna get hurt in the process? Probably. But you can't live every day of your life for someone else.
I dont believe that people are born depressed. Things in their life cause them to be depressed. Change your life, fix the problem.
