bleach breakage

Hello to all.  It's 2:00 in the morning and I can't sleep for thinking about my hair disaster.  So I got on the internet hoping to find a miracle and I came across this website.  I went to my salon tonight to get my usual hairstyle but tonight something went terribly wrong and my hairdresser doesn't want to admit it.  She colors my hair a dark brown and then puts in chunky blonde hightlights (stripes she calls it).  Sometimes my hair can be difficult to lift to the blonde she tries to get to so she puts me under the dryer then she always has to use a toner.  Well tonight she left me under there to long I'm guessing because as I was sitting in her chair I saw big mushy pieces of my hair falling my lap and on the floor.  She said thats okay, it will be alright and that you cannot help from overlapping a little bit of hair each time.  Well that was coming from my ends.  She should not have run the bleach through my ends again anyway.  She gave me some deep conditioner (on the house) obviously because she felt guilty.  When I got home and looked at it, all the blonde in my hair is completely fried.  I have big chunks broken off (like the whole chunky highlight is gone about where my ears start and lots of other broken pieces and very fried ends.  The brown looks to be okay.  She has done my hair about 5 times now and there has not been a problem until tonight.  What did she do wrong?  Leave me under the dryer too long?  She is not owning up to any mishap and her coworker also backed her up.  Now I'm stuck with this mess and until now I have had great strong hair.  My hair is pretty thick, long (midway down my back and naturaly curly but I blow dry and straighten it with a flat iron every other day.  I can't go without using heat on it until it gets healther because It's too curly and unruly.  Even when I used to wear it curly I would still need to use a blow dryer to style and tame it some and nowadays the curl it has is just horrible so I never wear it curly.  So what do I do now?  I am completely sick and sleepless over this.  It's dry and brittle and I am scared to even wash and dry it for fear of more breakage.  I have heard that color sometimes makes hair healthier, can I color over the blonde streaks with brown to try to hide the broken pieces better?  Is that even an option at this point?  I'm sure probably not so what do I do to help what's been done and prevent further damage?  HELP!!!!!!
