DOB 2-10-1986- Looking for siblings or BM/BF

closed adoption handled by Attorney Jeff Meyers (Myers?) Name at birth- Alissa Marie Campbell Married name- Alissa Marie Henricksen DOB: 2-10-1986 Place of Birth- Great Plains Regional Medical Center- North Platte, NE Adoptive parents names: Susan Mary Campbell and Richard Scott Campbell Adoption took place immediately after birth. I was told by a clerk in the attorneys office that my parents were married, and living in North Platte at the time of birth, and there are 2 or possibly 3 older siblings of record. I was told that my mother was Mexican and my father was Italian. I have early onset glaucoma, and a thumb with a tendon that wasnԒt formed properly. I am looking into surgery for both of those things. Also, my husband and I are dying to have children, and I have no medical history whatsoever. I have dental problems, and severe tendonitis in both knees and would like to have any idea of what to expect. I would like to have any information, about my birth parents or siblings. I have already contacted the county (both Douglas and Lincoln county) and they both tell me that my records are sealed and I would have to petition the government to have them reopened. And since my medical issues are not life threatening they told me that I most likely would not be able to access that information. I dont even have my original birth certificate from Lincoln County, only the one from Douglas with my adoptive parents information on it. Any help would be infinitely appreciated!!!
