I hate to lie to you, but I’m scared to say the truth

I felt like crying the other night. You asked me what was wrong.I said I didn’t know why. I lied. You asked if it had anything to do with you. I lied about that, too.
The truth is:
There are always many girls who like you. You don’t know why, you tell me you don’t understand. You’re amazing, incredible and the most wonderful caring person I have ever met. I know that almost all of those girls are prettier than me and nicer than me. And it makes me wonder why you’re with me. I’m no good for you. I’m a selfish bitch, I never do anything for you. You tell me how much I matter, but for some reason, I feel like you haven’t seen me for the bitch I am. You deserve so much better than me. I’m so afraid about how I would function without you. When I’m with you, my worries fade away. But, when I go home and lay in my bed at night, I can’t help but think about how much I don’t deserve you. You wondered once why I’m possessive. I don’t want you to realize that any one of those girls is better than me in so many ways. You are my everything, I can’t bear to lose you. I love you and always will.
