Suicide is understood by the Church to be against God's law. Although it is wrong to take one's own life, a person who commits suicide may not be responsible for his or her acts. Only God can judge such a matter.
Obviously, we do not know the full circumstances surrounding every suicide. Only the Lord knows all the details, and he it is who will judge our actions here on earth.
When he does judge us, I feel he will take all things into consideration: our genetic and chemical makeup, our mental state, our intellectual capacity, the teachings we have received, the traditions of our fathers, our health, and so forth.
