vent? Well, I always felt so mad it's driving me crazy. I don't have many motivation to do anything. I always kept my emotions hidden so I stayed calm most of the time, but the problem is that I don't know how to make them disappear. They just kinda getting piled there. I'ts stressing me out. Also you can play a silly pong game here.
