Janke covered the most important aspects of your case.
I find it odd your attorney office didn't determine your eligibility before having you apply.
If you are well enough to work while medicated, than it is unlikely that you'd be approved for SSDI. The "grid rules" go into effect at your age, but beyond those concessions for age, whether or not you'll be hired is not considered. But, these are non-issues until you prove eligibility.
Please read my post #45 in this link.
