Confused

I'm so confused about the thoughts running through my head. What went wrong, what can I do to fix it. How can I just get by without thinking about it without it plaguing my mind. How did everything get so complicated I just dont know whats going on right now. I'm freaking out I feel like I'm going under with all my thoughts. I just can't seem to get away from them even in my dreams. Just wake me up & tell me this is all a dream because this just can't be reality :/
