I'm sorry this had to happen to you. I know how it feels because something like this happened to me. And it happened to me at a silicon valley startup. Except the story ended differently, it ended up with me quitting. They were so angry at me that my mother died at the end of a quarter. But the same thing, don't worry we'll take care of you, followed by absolute callousness that was, worst of all, disrespectful towards my deceased mother.
The way I see it is now you know what your company is capable of and how they value you. You can find someone better to work for.
