Please help!!! How do I stop my bleached hair from breaking?

I made the mistake of bleaching my whole head more than two times in the summer plus I dyed it alot and had highlights put in with bleach. I let my hair rest for about 2or 3 months but then I had highlights put in with bleach the day after christmas. My hair is so broken. It has alot of breakage. Is there a treatment I can use that will stop it from breaking. I am so desperate and depressed about my hair. I think i am going to shave it all off and wear a wig. I cant afford hair transplants.
