teks: Oh, if only I could tell you how much I miss you. I'm sorry if I've made too many mistakes with you. I've disappointed you so much. I want us to be close like before but it seems impossible. I know we may not be like before but I still want you to be my friend, my close friend. I'm trying to change and get rid of my bad habits. I will learn to be more mature. I promise :') I want to talk to you but I'm still not strong enough. I'm still in the process of becoming a better person and appreciating you as a friend :')
