Roots coming in, time to make a decision!

Hi all, just looking for some advice. My hair is naturally dirty blond and 3B. I first got blonde highlights about a year ago and this badly damaged my hair. I have lost a lot of curl and keep having to cut my ends even now because they are straight. I flat iron frequently because the curl pattern is so off. I dyed it dark to try to help my hair recover. Now I have an inch or so of roots and I'm trying to decide what to do. I miss my natural hair but feel trapped having to keep it dark because the roots are a big contrast and I'm afraid of losing more length if I get it bleached again. Help!
