Was their behavior surrounding my illness unforgiveable?

OK, I was hospitalized with a mystery illness about a year and a half ago. What happened, truthfully, was that I was having constant, terrible diarrhea over the course of about 12 hours, and I collapsed from dehydration. I was unconscious when the paramedics came and had kidney failure. It looked like I was going to die. My boyfriend at the time and his parents were total @ssholes to me when they first saw me in the hospital. First, he accused me of attempting suicide because my landlord claimed she heard "yelling" coming from my apartment. Then, his mother accused me of having AIDS. As I was lying there presumably dying, all him and his parents could talk about was how expensive the hospitalization was going to be because I didn't have health insurance. I stabilized and was taken to ICU as a precaution, but him and his parents continued to act like total jerks to me. They came into my hospital room telling jokes about how I defecated on the floor. I tried to put a positive spin on things, saying the hospitalization was nice, almost like visiting a spa, to which he replied, "It won't be nice when you get the bill." When I was discharged after a 4 day stay, he drove me home, and was again insulting me: "Now do you believe us when we say you need health insurance?!", "You were acting funny when we found you in your apartment" (alluding to me defecating on the floor), "Is having a cat too much responsibility for you?" (he thinks I got sick because I didn't keep the litter box clean). Afterwards, he stopped talking to me altogether, but then several weeks later, he sent me an email acting like nothing happened and he wanted to be friends again, but I completely ignored him. Was their actions towards me unforgiveable? I honestly hate these people more than anyone I've ever met in my life. What would possess people to be so nasty to me when I had almost died?
