I am not licensed in CA and can provide only general advice. You should contact a disability lawyer unless you have had a more recent trauma or event that has caused additional damages. If that is the case ou should retain an injury lawyer. Good luck.
It sounds like you have two separate questions. With regard to you, I agree that you should consult with a social security disability attorney who can assist you. As far as a personal Injury case, it is too late for you. The second question is with regard to your daughter. If your daughter's brain injury occurred during birth or later in an accident, she may have time left to file an injury claim, depending on when the incident occurred and her age now. You should immediately consult with a personal injury attorney to determine how to help your daughter. An attorney can help your daughter get the proper diagnosis and pursue a case for her with no money up front or out of pocket from you. Many attorneys, such as myself, here on AVVO Provide a free consultation. Good luck to you both.
