hi.
I hope someone with some good wisdom will answer you soon. You need help
First of all, Is it possible you could get some help to see a neurologist ASAP?
First you need to have the seizure situation looked after.
And I thought the guidelines for repairing unruptured aneurysm are that anything above 6 mm, they will repair. Anything smaller, they just keep monitor.
You may need to look for a different neurologist. Look for a interventional neurologist.

as far as your employment goes, hopefully you can see a good lawyer.to look into the ligality of your job termination
Your employer has unlawfully terminated you as far as I know.
I think there is a law called " Americans with disabilities, where employer must make reasonable adjustment in your job disription to avoid the stress which is your situation
In the mean time, also get a lawyer to help with the dissability application
Hopefully you could get some help from the social section
