I had a test and I cheated on it.
What made you want to cheat on a test?
My friend told me he'd help me cheat
That's dishonest of both you and your friend. If you're worried about how you might do on a test you should do some extra studying or ask your teacher what you might need to know.
I have a lot going on in my life right now, I need to take care of my problems before I focus on school.
I am sorry about the problems, but that doesn't mean you can cheat. You are only adding to your problems if you get caught. Talk to your teacher and see if they will grant you an extension.
