You know it's about him

Just to let you know

I hope you know that even though my mental health is slowly getting worse you'll always be my favorite person. It dangerous really. My whole mood depends on you. Everything depends on you. Ill forget my entire opinion just so it is the same as yours. If you're happy I'm happy. If we barely talk I'll think you don't love me anymore. You are my world. I will do anything you ever wanted. I'd go to jail for you. I would murder for you. I would end myself for you. Anything..for you. You will forever be my person. My everything. Everything about me is about you. I have nothing else to talk about but you. Nothing else to think about but you. Nothing to even dream about..but..you..
