You're in trouble. It usually is said when caught in the act of doing something wrong, or anticipation of doing something wrong.
Assuming you're talking about something illegal.... yes !

A lot more than you would be if you just said who you got it from, especially when it is illegal.
An example of trouble is when you are caught doing something bad and you could get a punishment.
If you do something bad and you think your gonna get into trouble it doesn't matter. Once something is done or said, it cannot be undone. The best thing to do is take responsibility for your behavior, accept the consequences (punishment), apologize and do better in the future.
