Yes, I agree that you are definitely "too young to be a caregiver." I am sorry you are having to deal with these circumstances. You do deserve to be able to have a life of your own.

I suggest you talk to a social services agency about the situation and find out what resources might be available. Maybe you can check around to see if someone will be willing to stay with your mother at a reduced price. You might also see about getting into a mental health clinic at a sliding scale (you pay only what you can afford.) I hope these suggestions will be a start, anyway.
