In the book Nosso Lar, the main character is deemed to be a suicide.
It was not a conventional suicide, he just drank a lot and ate a lot of rich foods.
So with that criteria, many people would be suicides - smokers, drinkers, fast food eaters.
So in his afterlife, he ended up in a dark swamp, but eventually, he was rescued and sent to the spirit colony where he lived as normal.
My personal opinion is that suicide does not damn you in any way.
