And of course there was no unemployment insurance because the decision to leave was yours. If you leave the job through no fault of your own, after making a good faith effort to solve the situation and deciding there was no reasonable alternative other than to quit, then you have some slight possibility of drawing unemployment benefits. But it's relatively difficult to show that your work situation rose to that level, and that you had really exhausted all reasonable alternatives before quitting. If you had refused to do what they asked, and they had fired you, your chances to be approved would have been much better.

But in this situation, they asked you to do this, there was a lot of drama here, and you could have, at any point, have refused and let them fire you. You could have left at any time. It's not really the employer's fault you elected to say and be stressed to the point of headaches, extreme stress, mental anguish. A hostile work environment in legal terms is, as cbg has pointed out, not like what you have described. You need to simply move on.
