Seatmate always peek and copy my answers secretly and acts tough

Write some fake (wrong) answers for them to copy
Then quickly change them before you hand the paper in

In the long term you arent helping her any. There will be an time when she cant copy from you and will fail. There will be an time both of you get caught and this can have serious consequences. If youre her true friend offer her private tutoring , stop letting her copy your work. She is only being set up to fail by you allowing this. She must think you are smart otherwise she wouldnt do it. Talk to her in private , if she doesnt do anything to help herself succeed without copying you then move seats. Last resort is telling on her but that should be very last resort.

I intentionally give out wrong answers for people to copy from.

And change it when they are not looking at.😁

It's time to purposely fail

Dear diary

It's been several days since I've had an "episode". It took 3 days to clean up the blood.

I try to control my urges, but right now, I can see someone reading what I am writing.

Urge to kill..rising...struggling to resist smashing faces....
