Oh my head!! I’m broken! I’M BROKEN!!!!

AHHHHH! This is my first time on a Mac since a few weeks ago. In the last five minutes, I’ve tried to move my cursor to the bottom of the screen and wondered why my task bar didn’t pop up, tried to use my “return” key to send an IM, and tried to control-C something. I have been on a PC way too long. I don’t like this. I need a graphics job again. 🙁
