Dear mom and dad:
By the time you both read this letter, you'll know that I've decided to be reunited with Stan again. Why should I be left behind and in this much pain because of his death? I'm sure the two of you have noticed just how quickly my once bright outlook on life has dimmed rapidly since he left me behind, which isn't right or fair for me. Death's the only true way for me to be happy again and free of my pain filled grief.
Please don't reveal this letter's contents to my little sibling. Burn this letter after you've both read it, because it's a letter intended for just you two. I've already written out my suicide note in addition to this letter. My suicide note should also be burned after you have both read it, so my little sibling doesn't find it. I'm so sorry for the pain I'm about to cause you and my little sibling, but I'm not happy anymore.
I've included my last request in my suicide note, which I'm hoping you'll both honor. Again, please don't be sad for me, because I'll find happiness when I reach my intended destination. I want both of you to always keep my memory alive in your hearts, because that's where I deserve to be even after I leave my body behind. Dad, don't let mom talk you into finding me and keep me from ending my pain, because I know that's what she'll do.
I love you both, but living on Earth just doesn't have much appeal for me if it means having to be without my best friend forever.
Your loving son
