everybody lies in life, don't make such problem of it. It's a normal thing as a human being.. Of course not the nicest but people just lie
If everybody that lied would die, there would be ZERO persons on earth.
Don't make a problem of it, even don't make a problem of it if you fail. Study is not where life is about. Just enjoy the day, the birds and the sun. Yes you would get a brawl with your parents. So what?
Again if everybody who get brawls with their parents would die, the world would be empty.
You sound young, i hope you can get better distractions than these kind of forums (everyone is welcome don't get me wrong)
But it's not needed to read about suicide if you have lied to your parents, if you lied to your parents you can better look funny vids on youtube about interesting objects imo.
If you fail exams they will forgive you, not the same day but afterwards, 10 years from now you don't even think about any exam or parent stuff anymore you're just living life on your own enjoying your own 'family'. So by then you don't ruminate about all these 'school/parent' things anymore. Now it's a great object in your life, it will pass.
Think about that. Don't take your life at young age! Life will bring you joy and happiness later
Best wishes!
