Laid off and apprehensive

Tl;dr: laid off, possibly inexperienced, feeling a bit scared that i won't be able to even get in the door with potential new jobs.

Hey y'all, I was an 11b in the army when I was in, and was what many would call a "shitbag". I got out in 2012, bounced from job to job trying to figure out where I fit into the civilian world.

Fast forward a decade and I'm successfully working as an automotive repair technician, but my disabilities are making it difficult to perform core tasks of my job. I start VR&E majoring in business admin, minoring in psych, and using overlapping classes and electives to get a Human Resources Management certificate. I'm 60 of 120 credits through and I got laid off last week. From what I deduce, it's because I became hella inefficient that was the reason it was me that was voted off the island. What do "reasonable accommodations" even look like for a technician? So. I took it on the chin and decided working on cars is no longer in my best interests.

The meat of my concerns:

I'm afraid that I don't have enough knowledge/experience to completely pivot to a sitting role.

Does anyone have any resources i can look into? Words of wisdom? I'm in southeast Virginia, if that helps.
