You do not state your age, or what kind of "paper that got notarized," and those things might well make a difference. My guess is that she is receiving child support relating to you -- but probably should not be, from the situation you describe.
You can request a new Social Security Card from the Social Security office, if you cannot get your mother to respond to you. Absent that, you could have a lawyer send her a note and try to get her to be a bit more cooperative.
It might be good for you to consult a lawyer. If you cannot afford counsel, there are free consultations offered on Thursdays at the self-help center; volunteer attorneys provide 15-minute consultations, for free, on family law questions.
