We were approved at age 21 without a lawyer, but that was nearly 16 years ago. We had a lot of documentation from our pdoc and a letter from our T. Plus more than 15 hospitalizations over the years prior. From submission of the paperwork to approval was 3 months for us. We are diagnosed with Schizoaffective and a dissociative disorder as well though, and it may have be "easier" to get back then. We get reviewed every 3 years still, and they keep giving it to us.
