I kind of wonder that myself.
Seems like it is the one area that God told us not to get into. That of judging what happens to the soul of someone where the sin is not clear.
And if suicide is a sin and sin is actually one of desire then is "just let me die" also a sin?
Elijah was not reproved for it.
There is a verse about "why die before your time?" but that could also apply to being reckless with your actions or even not keeping yourself healthy by diet and exercise.
Do I think God approves of it? No. But just because something is not in our best interests does not make it a for sure sin.

1) There is a difference in allowing God to take your life and taking your own life. Being willing to die may be a great virtue; suicide is murder*.
2) Sexual lust, a sin of desire, is listed separately in the ten commandments, but it’s an exception because, no, temptation towards sin is not sin itself. Deliberately inflaming your lust is what makes it sinful.
3) Elijah, not knowing Christ, could not despair of Christ.
*Suicide is murder: suicide is a grave sin. But there must be three elements to a MORTAL sin: It must be grave, but its gravity must be known and it must be willingly committed despite that knowledge. Mental illness underlies much suicide, and is an impediment to free will. Thus, it’s very plausible that any given person who commits suicide does not commit mortal sin.
