Why do I cry every time someone laughs? Why do I feel like they are laughing at me?

I would have to say that this is the result of an over active imagination. Remember, when we view ourselves, things seem like a much larger deal than what they truly are as opposed to how others see us. There really isn't anything to worry about. Don't worry, most people are too wrapped up in their own lives to care about most other people anyway. I wouldn't think much of it, my friend. Best of luck to you!!
