Don't know what to do with my hair dye!?

Hey! I've been dying my hair since i was a kindergartner. Now I'm a middle schooler and want my natural black to come back. what i did in my life with dye was: hi-light my hair blonde, then redid that once faded, dyed hair red in 3rd grade, went back to blonde hi-lights, then re did it red, then in 6th grade i did blonde once again. and about 4 months ago i dyed my hair red again and i hated it. it was much too bright and wanted my old hair again. thank you so much if you can help me!!!
