Dear You,
Get out of my head. I can't believe you still 'control' my life, you were getting so much better. You stayed away for a while, but that guy made you come back. I don't want to feel empty and helpless all the time. I don't want to feel paranoid, all because you put pointless worries into my head. My friends asked me if I was okay several times today, I nearly started crying, but they wouldn't understand that you, my anxiety, is controlling me. Just let me live my life happily, that's all I ask.
From Me.
