妳可以向她解釋，說那不是妳做的，
或者妳可以幫他找回丟失的錢，證明妳的清白 ，
但是那不是容易的。
我希望這兩條建議能幫到妳。
給妳最美好的祝願。
I'm really sorry to hear you have been got wrong with your friend.
You can go explain, tell her you are innocent,
or you can find the lost money for her thus prove you are framed actually,
but it's not that easy.
Anyway, I sincerely hope my suggestions can help more or less,
wish you smooth it over eventually.
