Need advice!!! Please 💕

Okay so I got my hair done in October of 2018 like this..

And now my blonde has all grew out and my hair looks like this

I only got maybe 4 trims (barely any hair) the whole time since i went mostly blonde but as you can tell my hair is shorter now than it was then. 😭 My hair breaks off like crazy and I’m guessing it was from the bleach killing it. And the really dumb part of me wants to go back blonde so bad.

So my questions are, is there any ways to go blonde that won’t really hurt my hair?

Is there anything I can use to strengthen my hair that you have seen work?

Should I just embrace my brown hair and not go back blonde?

* also my hair is naturally curly and for the last year I have only put heat on it twice
