Although it's certainly not necessary, I consulted a social security attorney before filing my claim. I think she helped me avoid some of the pitfalls. Here's how it went:
November 3: Last day of work
November 13: Applied for SSDI online
November 14: Mailed medical records to SSA
November 16: Received email from SSA asking me to visit office to clarify "name or birthdate."
November 17: Visited office; clarified name (my childhood social security card used an initial instead of a first name); reminded them my application was under the compassionate allowance program for mCRPC.
November 28: Approval letter from SSA.
That's a load off my mind.
