I opened my computer up and found that I couldn't left click.

To fix the problem I managed to open up a terminal and I typed to command to restart my window manager. That solved the problem.

Then I closed the terminal. As it turns out, this was a mistake. All of the windows I had open were half broken and basically everything else was full broken. I had to switch to a TTY and restart my window manager again. This time with an "&" at the end.
