Your question is unfortunately indicative of a type of problem many people have had - proving US citizenship under these circumstances. You will need an excellent immigration attorney who can assist you with submitting all the required info as well as convincing the government that you actually are a US citizen. Be very careful with this issue as it may seem obvious to you that you're a citizen, but this is an issue which USCIS requires to be proven. You are going to need as much docmentary and even testimonial evidence as possible. Retain an attorney who can assist you with proving that you were indeed born here - a tough thing to prove if you do not have a birth certificate and no other contemporaneous evidence as it appears you do not have.
Look on AVVO for an excellent attorney with a lot of experience.

This may be a problem. There are a lot of phony Brownsville birth certificates where midwifes did the delivery. You may need to hire an attorney.
