You are not practically a worthless corpse, mister. So don't even think that, okay?
He saw worth in you. He saw what and who you could be. That's part of why he loved you.
Those eyes aren't closed. They're in your heart. They're in your soul. Gazing at you with love. His memory lives on. In you. And while ever it's there he will never be gone. The physical may be gone but what he meant to you, who he was, your love for each other... that will never leave you.
He would want the best for you, sweetie, don't you think? To see you be who you always dreamed of being? To be happy? He would want that. That was part of his love for you. To watch you grow.
Wanna know something? You already know I took my name from someone close to me who died, to honour her memory. I've lost most everyone important to me in my life, in terms of family. But they're never gone, not truly. And I do my best. For them. For everyone I ever loved, and everyone who ever loved me, to honour them. To make me, and them, wherever they are, never forget. To make them proud of me, and feel that even in death, I was being true to the person they loved, and who I loved in return. To feel like when I do see them again, I'll be able to tell them that I was a good person, and I tried to do my best in this world. To be the best person I can be... for them, as well as for me.
You can do that. He would want you to do that. So that when you do see him again, you can tell him all the things you did. How you took the love you both felt in your lives, embraced that, and used it to grow, to become the person you both wanted you to be.
