Mom took out credit card in my name to make it until next payday, not sure how to feel.

So long story short, things have been really shitty financially lately after a long sequence of events. It is just me and my mom and we have no one to ask in situations like this. Basically we have $20 until this friday and we need to pay for where we live and for food. My mom decided to solve the issue by taking out a credit card in my name which came in the mail today and just told me about it. I understand things are rough but am I wrong for feeling mad in a way because she did this without first consulting me? And since this is pretty much our only option it is probably not worth asking, but how good of an idea is it to do this? I guess its better than having nowhere to live and no food but still... I don't know, I need some cheering up and some advice I am new to the being an adult in regards to dealing with shitty financial situations

edit: she hasn't used the card yet and when I seemed upset that she did it without consulting me/asking me to do it she got angry/defensive/sad/every other negative emotion and played the "you don't understand I thought you would understand I don't understand why you are upset blah blah" card
