Pursuing what is quite likely wrongful termination/retaliation against a GIANT...is there anything to gain?

I was terminated after 8 years at the medical school/hospital of one of New York's largest universities 1 year ago.

6 years ago I reported sexual harassment and inappropriate behavior toward female patients by my boss, who was independently investigated and fired. I was the chief witness for my then employer at the trial and some co-workers/Drs were friends w/my boss and angry.

I am chronically/terminally ill due to a botched surgery performed at work. I did not sue b/c they were my employer.

When I was laid off I was told there had been complaints that I was out sick too often (I had used all my sick time, but had weeks of vacation time left) and my boss admitted it was from people who didn't like me because I had been a whistleblower.

Now I've lost my income and health insurance.
