Anxiety
Here's my view on what anxiety is if you've never experienced it.
Imagine hanging out with all your best friends. You're having the time of your life with them, it's a nice sun shiny day. Then, all of a sudden a dark cloud sweeps over you and all of your friends disappear and a recorder goes off in your head reminding you off horrible memories, tasks you have yet to accomplish, and insults that you've been told before.
When you have anxiety all the fun stops immediately and all you think about is the "bad stuff."
