She stole from me again

I checked my bank balance this morning, and the girl took my debit card to charge a game enhancement for her computer. She was told not to, and took it any way.
It was only $25, but in the state I'm in that is significant. I've just filed for bankruptcy. I've just lost nearly everything and what's left is pathetic. My credit cards are shut off, and only my debit card is left. If I run over, there is nothing to fall back on.
She does not understand the betrayal of trust involved, and thinks because it is only $25 that I should let it go and not be upset. 
I'm going to have to start locking up my wallet again. 
She stole from me again!!!
