This is for all of you who have had those thoughts, or who may know someone who feels or has felt this way.... and it is also for those of you who have never considered suicide, but might one day out of the blue be thrust into such thoughts.
I'm not going to list the usual reasons NOT to do so, to take one's own life regardless of the reasons. I am, however, going to tell you one FACT that should deter you from doing so.
Regardless of how hopeless your situation may seem, when you meet God in judgment, you will see how you could have handled the situation with perfectly clear eyes through God himself. In other words, if while alive you felt desperate, like in a maze with no exit, God will show you exactly how the exit would have been shown to you out of your dilemma and despair.
I've blogged about this before, about how if only Judas Iscariot had held onto life for three more days, he would have seen the Resurrected Christ and have sought forgiveness.
When you are judged by God, whether you are taken to heaven or sent to hell, you realize not only that there was a way to cope with your situation, no matter how hopeless or painful and, further, that even if you felt the most worthless person who ever lived, how someone in the present or the future would have needed you very much. Each and every person can save their own physical life and thus, through God, be open to Him saving his or her eternal soul also.
DO NOT BAIL OUT. Trust God and genuinely open your heart to Him and Him alone.
I hope this helps.
Through His Holy Name.
