Can you check the mistakes in the following paragraph please?

One day, at primary school, a stressed and bored nine-year-old girl didn’t know what to do as she found school lessons really uninteresting. So she decided to do something amazing to surprise the teacher; she sat down on the window sill and started talking: “I’m so depressed! My life hasn’t meaning (or hasn’t got a meaning, or is meaningless)!”
After that, the girl jumped out of the window (or the second floor window). (or Her classroom was on the second floor).The teacher risked a heart attack. Luckily, she discovered that under the window there was a balcony and the girl had jumped on it. Naturally, the teacher gave her a very bad mark, but all the students really enjoyed it.

Thank you for the help!

My life hasn’t meaning (or hasn’t got a meaning, or is meaningless)!” = either the first or third, but for the second = has no meaning...

Here are the corrections for the paragraph:

One day, at primary school, a stressed and bored nine-year-old girl didn't know what to do as she found school lessons really uninteresting. So she decided to do something amazing to surprise the teacher; she sat down on the window sill and started talking: "I'm so depressed! My life has no meaning!"
After that, the girl jumped out of the window. (or Her classroom was on the second floor.) The teacher nearly had a heart attack. Luckily, she discovered that there was a balcony under the window and the girl had landed on it. Naturally, the teacher gave her a very bad grade, but all the students really enjoyed it.

Explanation on how to find the mistakes:
1. The phrase "hasn't meaning" should be corrected to "has no meaning" or "has a meaningless".
2. "Jumped out of the window (or the second floor window)" - This part is confusing because it suggests that the girl jumped out of two windows. The correction suggests a single window.
3. "Risked a heart attack" - Instead of using "risked", it should be "nearly had a heart attack" to convey the intended meaning.
4. Addition of the phrase "under the window" to clarify where the balcony was located.
5. "The girl had jumped on it" - The correction replaces "had jumped" with "landed" to improve the sentence's clarity.

Remember, proofreading is crucial to catch errors in your writing. Reading your text carefully and paying attention to grammar and sentence structure can help you identify and correct mistakes.
