Undefying emotions

There are some emotions that Ive been feeling. i don't know what they are or why they're all of a sudden trying to get out? there seems to be something inside of me screaming out for help, but what could it be? would this be the emotion i cant define? i wake up in the middle of the night crying, but why? theres something the matter with me. i just don't know what it is? I'm so full of happiness and laughter, right? so, what could be so wrong? is what i call happiness and laughter really a front? all these unedifying emotions are rolling around inside of me. they want out, but i prefer to keep them in. I'm worried that if i let them out, then there will be a bad outcome. these emotions are what i call my unedifying emotions.
