It's not clearly written in the Bible what happens so we don't know.

Even tho taking your own life is a sin, we can't be sure where we will end up. I heard a story about a saint called padre pio, he is a catholic saint that has the ability to see which soul made it to heaven or hell. So 2 married women approched him with the same question "my husband commited suicide, is he in hell?". Believe it or not the answer for both of them were yes and no. The husband of the 2nd wife did infact made it to heaven after repenting in his last breath after jumpinv off a bridge

I didn't practice 😆
