You could have used your account yourself, earn yourself and then help your friend but you didn’t. It is pretty stupid to let some other person access your account.

I somehow believe your story because even if you told us something else it still wouldn’t make much difference.

You could have said:

“I have plagiarized father. I confess. I am guilty. But I haven’t plagiarized again in the last 999 years after my last offense. Please abolish me from my offenses and gimme my account back. I know your merciful. Gimme a second chance. Godbless. Amen.”

And you would get the same response from the guy who decides on these stuff.

Your fate is in the hands of god now.

Pray.
