What to do with my trust?

Your issues are unrelated.  The trust has nothing to do with citizenship or birth certificates.  If you have the trust documents, a lawyer can tell you what to do.  As far as a birth certificate, the process to get it depends on where you were born.  While money can help a citizenship application, that is not needed if you were born in the USA.

Sounds like you have several issues here- and much more information is needed in order to address any of them. How do you know there is a "massive trust"? Who are the beneficiaries, and who is the trustee? If you have the trust agreement, that is the document that tells the trustee (the person in charge of administering the trust) what to do or what can be done with the trust. However, reading a trust agreement is not a substitute for some guidance from an attorney.  Finally, if you have good reason to believe that you are the beneficiary of a trust and the trustee is not providing you with money/assets to which you are entitled, or information regarding that trust, a court can compel the trustee to give an accounting, and many other types of relief, to beneficiaries of the trust. With regard to the rest of your questions, birth certificates are almost always sealed in connection with adoptions, although laws are being proposed in many places, including New York, to give adopted children the right to their original birth certificate information. You did not mention if this is an adoption situation.  If you were born outside of the US, you would need to seek counsel in your place of birth regarding the unsealing of your birth certificate. As far as passports, you can contact your local passport office for information about all the documents required for getting a passport.
