I TOTALLY screwed up my hair with hair dye. HELP!?

Ok, so a while ago, I dyed my hair black. I REALLY liked it. The dye is semi permanent. I did it maybe 3 times? Just kept redying it. Then about a week ago, I was like ok now I want to go blonde for the summer. I got color out, and it just took the color out of my roots where the color started fading because my hair started growing. Then I stupidly put blonde dye in, and it ONLY died my roots and where the color out took the color out. I looked like a yorkshire terrier to put it simply. I'm dying to dye my hair blonde. I've done every other color you can thing of. Literally, half the rainbow. Anyway, I used 2 boxes of hair color out yesterday and two today. It started taking a lot of the black out but there is still a lot that isn't out. I look like a freaky punk rock kid because the color out is working and stripping the colors out one by one. Right now my hair is blonde (which i accidently used permanent color that the color out isn't taking out...), black and pink. HOW CAN I FIX THIS?! Don't get me wrong, i like the way it turned out at the moment because of the color out, but my mom doesn't... i look like some punk rock kid. But I want to try and go back to my original light brown hair or blonde. What do I do? I also want to cut my hair to help it since the color out KILLED my hair. Any SHORT looks for thick curly hair? (I do straighten my hair) I'm trying to do a 360 this summer. I want to lose weight, change how i look and everything. HELP?
