Hair problem

I dyed my 3b curly hair 2 shades lighter from dark brown yesterday, my hair is suuuuuper dry. It feels hard and not soft at all. I'm seriously freaking out and might cut it all off. I tried castor oil, coconut oil, and deep conditioners without sulfates and silicones. I'm freaking out, and crying in my mind! Anyone went though this before? Help help help hellllllllpppppppp! What do I dooooooo?  😢
