Zero, Nothingness, Suicide, and Buddhism

I have struggled with "suicidal ideology" for years. And years. My therapist has never said my suicidal thoughts and wishes and fantasies were delusional, but I think they are. I just have never been able to formulate a logical and convincing argument against suicide. All the pablum usually offered up by self-help and programs and Oprah sound nice, but never touch the deep truth that I believe suicide would end my suffering. Tonight I realized that suicide is a "flat earth" option - a delusion.

If someone believes that the earth is flat, they might ask "will I fall off the edge of the earth if I reach the end? Or will I run into a wall of sorts?" The questions themselves are silly to those of us who believe the earth is round, but to a flat earth believer the questions are valid. So it is with suicide. My belief that that suicide will end my suffering is based on a grasping notion of both "self" and "finality." I grasp at this idea that "I" suffer and that death will bring an end, but that's silly. "I" only exist in this moment and this moment ends. Then this moment ends. Then this moment ends. My suffering is endlessly ending.... The delusion is that I believe in both a self and an ending. But that is flat earth thinking. Perhaps the earth is round.

Zero is nothing is round. I had an algebra teacher that spent an hour once discussing the concept of zero as an assumption and as such was proof that God existed. Buddhism, in my limited understanding, is all about nothingness but not at all about God. Wouldn't it be ironic if nothing was proof of God?
