bleached, dyed, short, curly, dry, damaged hair

Ma

my hair is naturally dark brown. I've dyed it a number of times and then decided to let my friend bleach my whole head. it was horrible so I dyed it back brown. its now faded to a very light brown almost orange with my dark brown roots. i also just got bangs which are completely botched. its almost like half of my head is bangs. so now I'm left with a complete mess on my head. what should i do ?????
