This is amazing!!
You've described it accurate, too. Is this poem about you? Or did it come to you?
Either way this is actually realistic, the decision to live or die, when I put myself in that position I picture my funeral.. how people will be sad, my mother, father, borther sisters, how I would have caused all this misery because I couldn't cope with myself... It makes me fell extremely selfish... and to think that others have it worse than me, people are fighting for their lives, people are living on the streets, some people have noone and still being optimistic.. I saw this one story of this man who shot himself in the face, attempting suicide, he survived, he's homeless, his face isn't attractive anymore, you can't tell that he has a nose, but he smiles, and he says "One shot will do, I know that I was meant to live"
There is someone called Nick Vujicic he's an inspirational speaker, he talks to all generations, he helps teenagers with eating disorders, he helps cutters, boys with eating disorders, he's just extremely inspirational! But there's a reason why... He has no limbs (no arms or legs) and at the age of 8 he attempted suicide, but he prayed and he prayed, he still doesn't have arms or legs, but he can do loads, he can dive, he can play football, he cal do anything he can put his mind to. here's a link
You are definitely improving as a writer. Your imagery is becoming more and more unique, intricate and interesting. I think the last line wraps it up perfectly. This poem renders the perfect amount of emotion to reflect experience.
