How do I find lawyers that are licensed to practice "federally" or across the USA?

Unfortunately, my case was damaged from day one by the social worker that filed for me. I have a comprehension disorder and I had to have help with all of the applications and paperwork. I hadn't been afforded access to real medical care for sometime and the records of past care were irretrievable . I did start getting official, current diagnoses with testing within my "dates insured " but it was obvious that the judge did not have my records and test results read by a medical professional . She even contradicted herself in her ruling and she left out the vocational experts final word in the denial! Long story about the damage done but now the only way I can get my benefits is to have the case reopened on the federal level or go back to work for 6 years which isn't an option. I am paraplegic and have 2 neurological diseases. (among many other diagnoses both physical and mental ) I really can't handle much more of this and am falling apart. I have no help now... who can help me?
