Suicide shaming by calling it selfish or being a quitter is only said by people who don’t want you to do it.

They’re trying to stop you.

On a basic carnal level it’s for their own sake not yours. You disappearing will make them sad and they’ll have to get over losing you for a while. Grieving. They don’t want to go through this and have their life disrupted.

So the solution? Shame and guilt you into sticking around even if you are miserable. Often nobody and nothing can really help you when you are in this mindset. It’s like being dead while you’re alive. You’re basically already dead and just making your body catch up.
