BRAKES ARE GONE.. help

So 2 days ago when we got that snow storm i was on my way home, when i hit some snow on a bend and bumped a curb with my front left tire. Shortly after, i realized that my brakes where pretty much out and my hand brake light is always on. Im not sure what has happened to the braking system but the brake goes all the way down to the bottom without slowing down. I have checked my dot 3 oil and even filled it to the top.

its not loosing any fluid but at the same time there is no responce from the brake at all

can anyone tell me whats going on?
