It's a big loss, but, I think that beyond the money, the important thing is also your stability and tranquility.
I have also read several things. The best thing, in my personal opinion, is that you take some time. Really reading negative posts will not do you good.
It's good to know what could have happened, it will help prevent it from happening again. But, I don't know about it, so I don't know if you can get to know.
I hope you will find out what happened one day.
