I have second hand experience of the first one, none with the second, and first hand experience with the third and fourth.
First of all *hugs*, I know it might not seem like much, but remember that you are loved. Second, bullies are dumb as they don't realize that bullying someone else doesn't change their situation. Third, try to get some work done....I also have some work I need to get done after this.
Fourth have a cat!
