Quit my job on the spot

Yup, I woke up this morning unemployed. I work from home, and have been for over 2 years. Yesterday my supervisor called me to tell me the president of our company is mandating all work from home employees go into the office at least twice a week. Wouldn’t be a problem except for the fact the reason I work from home is because I have to care full time for my disabled husband. He suffered a massive stroke 2 years ago, left him paralyzed on his right side and unable to speak. He is doing as well as he can, speech continues to improve every day, I’m so happy about that. He can’t walk, can’t go to the bathroom by himself, can’t care for himself at all. I emailed the prez asking why he was making this decision, did he think my performance suffered by working from home. He replied that it wasn’t me, I’m certainly a good employee but the company is “changing directions” to be more successful, which he said means he needs more bodies in the office and that he understands if I want to resign. Told me to let my supervisor know if I intend to work up to the implementation date. So I emailed my last time sheet, told him to have someone come pick up my computer because I’ll never step foot in that office again. I also told him his callousness in regard to my situation disappointed me to a level I didn’t know existed up until that point. I was pretty proud of that. I didn’t want to quit, I wanted him to officially fire me but I couldn’t stomach working one more second for that prick. So I can’t get unemployment but we’ll be ok for a bit, I’m a pretty good penny pincher. I just don’t know if I have it in me to pursue anything further, I’m thinking for my own mental health I should just drop it and move on.
