Sable in all likelihood you will receive a short form to start. It is important you continue to seek appropriate treatment, but SS only asks for info going back 12 months from the time you receive your CDR. Working pt or going to school or stating your condition has improved on the short form CDR would all trigger the long form CDR.

This is an excellent guide to read before you fill out the short form CDR: http://nymakesworkpay.org/docs/Guide_CDR.pdf

It explains why you should never use the comments section of the short form or update personal info.
