Do Christians who commit suicide go to Hell??

Not sure if this is allowed but I’ll be killing myself in August.

I’ve been a Christian since I was born but became really serious about it in 2024 when I was 15. I trust God wholeheartedly and I know he has a plan for me and I know that by going against it I’m sinning gravely but I’m really just done and wanna be finished.
So I’m curious to know what will happen to me?

There’s no way I can be talked out if it so I’m dying to know what will become of me, I really don’t want to go to Hell.
