I'm really sorry. I don't think I can live like this. I still don't have any real reason to live. I'm really sorry I made you sad, but I honestly feel like this is the smartest option. The only real reason I have for staying alive right now is that I don't want to make you sad. I'm honestly not sure what I'm going to do, so don't get too sad too soon, but in case it really is good bye...
Getting to know you and spend time with you was amazing. I'm really glad you've let me play and watch anime with you, and I want to thank you for putting up with my overbearing and cringy "you're the cutest" and "I love you". I want to say, I tried my best to avoid saying that and only did say it when I couldn't hold it anymore.

You're great. Keep being yourself. If, for some reason, you ever feel useless/unliked, please try to remember this. You made me feel great. Without even meeting me. You are and will always be more special than you might think.

I won't say "don't be sad" because I know that's just not possible. But I would like to ask you to remember the good moments.
Please don't feel guilty. I had planned this before I met you. It's not your fault. It really isn't.

Thank you.
