ACQPL,
You've not let everyone down. Not me at all. As long as you're alive, I'm not disappointed. I love you because you exist. Don't leave because you think it's better for anyone, because it isn't. Even the people I have nothing for at all, still matter to me. Even the hurtful people, through all the damages done, still need to be part of the Universe if only in a Yin/Yang way. My ex let me down, in that I trusted her and she abused it. She hasn't let me down because she's still there, as an example.
You matter. You are wanted. My very few friends mean everything to me, even though we're not super close or even very close. You have not let me down. Be here, be human, be love
