HELP PLEASE

1st picture is my hair now and the other 2 are before. Basically I was a full blonde then added some black on then underside and money pieces (not box dye I swear) anyways, I wanted more black so I had someone give me black stripes as you can see in newest picture. BUT there was so much run off and my hair feels ruined and like there’s no blonde :( is there anything I can do to brighten those spots again without bleach rn

I will add, it was overall darker but after a few washes it’s gone down but it’s stayed stagnant now. I feel so ugly and I lowkey am hating it more and more everytime I look at old pictures, please help
