Can I sue my boyfriend for kicking me out after I had a heart attack?

I have been living with my boyfriend for a year and a half for 18 months. He has supported me all this time. On November 17, I had a heart attack and had 2 stents were put in my heart and have to have 2 more in about a week. I came home on the 20th then on Thanksgiving morning, he sent a text from work telling me to get out soon and be gone before he gets home. I had no car, no money and nowhere to go and still recovering so I am now homeless. He’s caused me a lot of stress and depression. I am not on the lease but the landlord said I could live there with him. He was paying an extra $100 a month for me to be there. I am supposed to rest and recovery is 6 to 8 weeks. I had to pack all my stuff and move it outside by myself which could cause another heart attack.
