HELP PLS- Prius won't turn on!

So a couple days ago, my brakes were making a grinding noise when I pressed the brake pedals. I drove the 8 minutes it took to get home and made an appointment to get my brakes fixed.

Today, I got in my car to take it to the shop and my car isn't working. When I press the brake and push power, the car stays in accessory mode as if I never hit the breaks while I was pushing power. The dash comes on, the power locks work, the key fob works, and the windows roll down. But it won't shift into any gear, the power button light is orange, the air won't come on, the radio won't play any sound, and a lot of dash warning lights are on. Hoping someone might know what this could be before I have it towed to the garage! Thanks for any info!!
