SOLVED. Girl forgets memory [s]

[Becky]

I think this was a teen book. Don't remember Author or character names. All I remember is that the girl loses her memory, it is not " Memoirs of a teenage amnesiac". It was fiction book and it wasn't comic or manga.

I think the girl was involved in a car accident where someone hit her while she was walking? Apparently she was quite wild and broke instruments and was quite hated before she had the accident or something like that for things she done to people, but she can't remember any of it. I think she was quite fond of the violin or something or broke someone's violin...? I think she gets put in a new class and everyone hates her. This is all I can remember

I don't think the book is that old. Perhaps 2005-2007? It is set in this era, nothing old

Found it. It is called 'kat got your tongue'. Bit of extra googling helped!
