NOOOOO my script's content entirely gone after computer crash

Sorry for my BAD English, because English is not my mother language.

I edited the script, then quick saved, and well then my computer crashed, so I force the computer to reboot.
After that, thousands of rows (well, about 1400~1500 rows) of codes WERE GONE, dammit.
I tried refreshing and reimporting the script, but it did no work, the contents are still missing.
Fortunately (?), the size of script is 97KB, that means (well maybe) there’s still hope to recover the file, but how? Please help!!

you cannot fix this. This happens to every. Im very sorry my brudda lol. But seriously, try refreshing your computer / loading unity again. I probably won’t work but its worth a try
