I don't feel like suicide is selfish because we can never know the person's true feelings in that situation. 

It is difficult for us to relate to mental pain and empathize with what someone so afflicted is feeling as human beings. I believe this is one of the reasons suicide is so stigmatized and misunderstood. Most of us can easily understand physical pain since at some point or another in our lives we have experienced some form of it but mental pain will forever be difficult to understand.

But I also believe we should all push forward and be the best we can be.
