No, D.C. is not a problem at all. And yes, it's beautiful here. I don't know how folks on the east coast can stand all the traffic and people! I live in a remote, rural area, and go to Seattle no more than once or twice a year.
In regards XXXXX XXXXX in your face, there may still be time to file a police report for assault. If the police don't want to take the report five months later, you may want to try talking with a criminal prosecutor. I'm afraid, however, that as a criminal matter, this would be consider a very minor assault, and that would be the case with a civil matter as well.
Depending entirely on all the other factors involved, you may have a claim for disability discrimination. You need to act right away if you want to file an Equal Employment Opportunity Commission (EEOC) complaint, since (I think) the deadline is 180 days from the most recent discrimination.
You can contact the EEOC here: http://www.eeoc.gov/ (there's a ton of great information at this website!).
You may also want to talk with a couple of employment attorneys, in person - someone with at least five years of experience.
Here is one place to look: http://www.dcbar.org/for_the_public/working_with_lawyers/find.cfm
Here is another, in Maryland:
Don't actually HIRE an attorney without first checking references. And don't try to pick the attorney's brain on the phone. Schedule an appointment and visit the office, like you would for a doctor!
Disability discrimination cases can be brought not only for discrimination against a person for a disability, but also if the employer thinks someone has a disability and treats him or her badly for that reason, even if the employer is mistaken.
If there is still time for EEOC to take a complaint, file one. Filing a complaint with EEOC, and, if you don't settle the matter first, obtaining a "Right to Sue" letter, is a mandatory prerequisite for filing in federal court.
(If you worked in one of the states near DC, file a complaint with the discrimination agency for that state, and ask the agency to automatically file a complaint with EEOC on your behalf). Again, time is of the essence.)
Meanwhile, I hope that you are able to find another job. A court will expect you to mitigate damages by doing your best to find another job, and it will be helpful to have records of your efforts.
In addition, before you go see an attorney, or contact a state or federal agency, it would be helpful if you would write out a chronology of major events in your work history. Start with the date you applied, include your hire date, dates of all evaluations, and dates of all other significant events. Don't make it a book - just a list of dates, followed by one sentence describing the event. Keep in mind that whatever you write out can be used as evidence for and against you, so make sure it's accurate, and put the date that you wrote out the chronology on the document.
I'll be happy to write some more if you have some more questions. I work from home, so please expect a few breaks here and there as I do my household chores, etc.
My very best,
