What happen to my money in FTX?

I'm a concerned investor who has lost significant sums in FTX. What exactly happened to my money? Was it mismanaged or was there some form of fraud involved? I'm really struggling to understand how a company with such a reputable history could have allowed such a catastrophic loss of funds. What are the authorities doing to investigate this matter and ensure that it doesn't happen again? I'm feeling extremely frustrated and helpless, and I'm sure many other investors are feeling the same way. Please provide us with some clarity and direction on how we can proceed from here.
