File for unemployment compensation. Even if you are declined, you have a right to appeal. In the meantime, you should consult in person to see if your rights have been violated because of your whistleblowing.
It all depends on how serious the abuse was. As Ms. Goldstein notes, apply for your benefits and see what happens. It also sounds like you may have some whistleblower or retaliation claims, and you can sometimes threaten to bring such claims in order to get leverage for your unemployment claim. I suggest you speak to an experienced employment lawyer. Most of us will provide a free consultation.

Go ahead and file for unemployment. There is no harm. If no reasonable person would of stayed there under the circumstances that you describe to Employment Security, it is likely that you will receive benefits. This is something that should be talked over with a lawyer.
You should also be speaking to that lawyer about potential retaliation and other claims you may have against the company. The precise nature of the whistleblowing you did, etc., is critically important to the determination of whether or not you have a claim. Therefore, a face-to-face meeting with an attorney is important.
If you found this Answer to be helpful, please mark it as such. Remember, however, free advice is worth every penny you paid for it. This is only generalized commentary on your question. It is not to be taken as legal advice. I am a lawyer – but not your lawyer! Even "in person" interviews leave attorneys with plenty of questions – the Internet makes it crazy!
