HELP PLEASE!

First and foremost, you need to obtain an electrical permit from your local taxing authority. The permit and inspection in my locale would run ~$250.
Then, and only then, can you shove more wires in that overstuffed ceiling box.

A permit to add lights in your own house. Are you mental?
