"like the bible says"?????
If you did find something in the bible that addresses suicide, then our OPINIONS shouldn't matter. The fact is, we don't know what happens to someone who commits suicide.
Ecclesiastes 2:17 "So, I hated life..." this coming from the wisest person in the world.
Luke 14:26
John 12:25
In no way should it be considered that destroying what The Lord created is okay, and the only person who would actually willfully commit suicide is a murderer.
I was suicidally depressed for 51 years and I never committed it because I'm not a murderer, that doesn't stop some people, but God looks at each person' heart. Life on this earth is certainly not all it's cracked up to be, everybody (most people, human nature) does things for the sake of ego (all is vanity) instead of altruistically for the beauty and wonder of life, there's no real respect for truth and love or absolutes. Things only make sense by following a certain type of logic, line of reasoning (scenario), otherwise, it's all senseless/meaningless, just striving after the wind.
This world is certainly no heaven, but The Lord never gave us permission to leave it prematurely.
The more a person notices that this world is "certainly no heaven", it seems they have a special affinity for The Lord's kingdom. My opinion is that The Lord can appreciate such sentiment (no exaggerration) and would like to have more conversations with them. Committing suicide would be a willful and reckless destruction of The Lord's property (in their case it's not a crime of passion, it's a crime of despair, but a crime nonetheless...willful destruction of The Lord's property). No matter any human opinions or logic on the matter of suicide, The Lord will be THE JUDGE (the one making the decisions) and only His rationale matters.
