MiniMTV's journey

I recently resigned from my position at a company in Virginia after giving them four months' notice, thinking it would help with the transition. My last day was initially set for June 5, and I even received a temporary pay bump for staying on. However, things took a turn when HR informed me that my last day would actually be May 31, just after I had presented at our annual meeting for four hours. They also refused to honor my vacation days that my boss had approved, opting instead to pay me out. I had to resign due to health issues stemming from the demanding workload, which included consistent 10-12 hour days without support. Now, I'm wondering if I can qualify for unemployment benefits given that I resigned under these circumstances and wasn't let go for performance issues, as my review was quite good.
