My teeth have already moved from my braces?

I got braces on thursday morning, and its been 3 days and it hurts soo bad. Ive been taking medicine but it only helps a little. My gums are really red, and above my top front tooth, you can see my gum is extremely red and even has a little cut in it (i think from the tooth moving)

You can notice that my teeth have moved a lot. My 2 canine teeth were up really high, and in a matter of 3 days theyre almost level with my front teeth. The pain is so bad sometimes i want to throw up. I cant even eat anything, but last night i had to eat something solid because i was starving and felt sick if i ate anymore soup. When will it stop hurting? And also, when i chew my teeth dont go all the way down. My front 2 teeth are resting on my bottom brackets, so my other teeth dont touch, making it almost impossible to chew. (Im guessing this is to fix my overbite) please help i cant take this pain anymore. I want to eat like a normal person without crying!!!
