No matter how bad things are, don't just jump out a window and waste your life and your potential.
First, you need to locate a vary fine piece of wire and tie it around your neck, and to your desk. Then, cover your hands in super glue and place them on the sides of your head. THEN jump. Aim for something soft.
When you land, this will create the illusion that you pulled your own head off. People will find this entertaining, and you can die knowing you will contribute more to the world in death than you ever did in life.
