I would actually use this as an opportunity to analyze what attachments you may still have to this life. If you're concerned with how you look while dead, you're still closely attached to people's opinions (IMO) so perhaps you're not yet ready. Not that it's my place to tell you that you're not ready, but I mean, the chances of completing when someone is still actively and frequently thinking of what others think of them seems pretty low. There will continue to be something within you that isn't ready to depart yet - some people always have an audience in their head, whether it's an imaginary individual or individuals, which are typically versions of real people they know, and often even when not conscious of it the wannabe suicider will feel a pull in some way shape or form to stay here due to that mindset. Be radically honest with yourself. I have worked hard to get rid of this tendency. I have radically forced myself to stop caring what others think and it's to a point that I'm wearing sweatpants in public, something I never thought I'd do, lol. Being ready most likely isn't a "pretty" site, but it's the best launch pad and IMO involves completely letting go of caring about others' opinions. It's a good first step at least.
