Any Advice for Hearing Level Denial Claim

Hello,

I am reaching out cause i am about to have my first hearing coming up in May. I am currently a 32 yo male who was shot by a guy in the left thigh from behind post altercation. Long story short my disability includes partial detachment of my lateral quad and ptsd and anxiety. I have trouble walking and my leg gives out from standing for short periods of time and after sitting for short periods of time.

I was on medical leave with my job Amazon, and after receiving permanent restrictions 2 years after my injury, Amazon could not even find me a position due to my permanent restrictions. In result they terminated me and i lost my health insurance and have been waiting for this SSDI.

I have been denied twice and coming up on the hearing i have spoke with a few SSDI attorneys and all of them deny me strictly because of my age. I am here looking for advice because it seems like i will be going into this hearing without any legal support. Anyone who has done the hearing without support what advice can you give to help me get approved?!
