Would I have a strong case for collecting unemployment benefits in NC if I quit due to an extremely hostile work environment?

While employed at Interventional Pain Center for the past 1.5 years, I have been taken advantage of, belittled, dehumanized, verbally abused, harassed in front of patients and staff and have undergone weekly and at times daily panic attacks and severe depression as a result of Dr. Desai and the manner in which he conducts his place of employment. On top of an already stressful work environment, his out of line remarks and uncalled for interactions have managed to make my life a living hell. I feel trapped. I am expected to handle a ridiculous amount of work surrounded by absolute chaos and stress. I am expected to perfect a job that is loaded with work for 2-3 workers and told how useless I am when those expectations are not met to his satisfaction. I have went to my HR dept, Operations Supervisor, and anyone else who will listen to me at least 6-7 times and no positive changes are made ever. I am on the edge of a break down each and every work day and management is aware of this.
