I was lucky and did not have to appear before the ALJ. He reviewed my case and made a positive decision. SS has 60 days to send you the money and I got mine about a month later.
Assume that your lawyer has or will coach you. You do not want to say anything that will hurt your case. When a lawyer takes a case on contingency (I assume that is the case) they have to feel pretty certain that the case is winnable. Otherwise they are wasting their time and money.
Good luck and prepare yourself as best possible. Remember that SSD is based on your complete disability and that you will not be able to work for at least 12 months. Even if you have some ability to work but are unreliable due to your illness that usually qualifies as total disability. Any case is decided on disability, not your need for money.
