Un mensaje para mi mejor amigo en ingles?

Dear (name) .

Since the day I met you, i can't stop smiling, you were always by my side, and I'm so happy about our friendship, you can count on me anytime, tell me everything.

If you kill someone I would be pleasure to help you hide the body and make it look like an accident, I just hope that I mean to you, all that you mean to me, I hope you always stay happy.

See ya!

Pos espero que te sirva xD.
