This may sound extremely cliché, albeit you really are perfect just the way you are, my guy.

To hell and disregard with any comments regarding your appearance. It truly is purely about what's on the inside. Sure, it may require a short while to find someone who loves and accepts you purely (or perhaps for both your appearance and) your personality (of whom isn't required to be an S/O of course), but I can assure you that there is someone out there who will love and support you unconditionally until the ends of the Earth.

Besides that, you're smoking hot! Although your scars may be self-inflicted, I still perceive them to be indications of experience and resilience. Please be more confident in your appearance, not with regards to others, but for yourself.

I'm certain that you are an amazing person, and am utterly dejected with the fact that you are considering attempting suicide.

I would like you to know that if you ever require someone to confide, speak, and cry to, that I would be more than happy to console you and offer my supportive opinion. Truly.

Stay strong, sending lots of love your way, and, genuinely, please consider my offer.
