Drut,
I hope my situation gives you some hope. I lost my job a year ago in a similar manner that you lost yours. Though mine is a different job, I found work at a place that was willing to 'work different'. I hope that wherever you are hired is innovative enough to realize that they can benefit from the many good things that are the flip side of NVLD.
Right now, you are probably angry and scared, and I don't blame you. I am not sure I have completely forgiven my last employer, given that my current manager is so much more awesome. The time you spent at school is never wasted. You have learned a lot, and your failure at this job is part of your learning. The more important thing is that you have seen what has gone wrong, and can hopefully get some coaching to set up a game plan to navigate them. You might even find that something as simple as getting tinted lenses can help. Or 'telling yourself' what to do, so that you can translate visual items into auditory info, so you can process the world better.
What I would focus on now is getting a job to stay employed, ideally in your area. Focus on the positives that NVLD has. I had to do that with my AS last year, which I was convinced was actually NVLD while I was applying for new jobs. Talk about your skills with your new supervisor and invest the time necessary in doing this preemptively so you don't get fired. And keep your 'self observations' in these talks positive, so you can keep your sights on what you do well and how you can accommodate your weaknesses. That has meant my job to me, and I hope that it will help you.
If you have questions, I am always happy to help.
