My parents threaten to disown me over my conversion - need advice, please

As-salamu alaykum. I'm an 18-year-old college student in America. My parents are Hindu, and about a year ago I embraced Islam. Since then I've been practicing, and they don't approve. For a couple months they've been passive-aggressive about it. Before they knew I was looking into Islam I went through a rough patch where I missed classes and wasn't productive. For the last 2–3 years (including roughly a year since converting) I've pulled myself together - better grades, attending classes, getting fit, cooking for myself, and generally acting more responsible. I also started trying harder to improve my relationship with them; we used to barely talk, and I've been working on that from my side. Recently they told me they will kick me out unless I give up Islam. If they do, they'd cut off contact and financial support. I love my family and don't want to lose my parents and brothers. At the same time my faith matters a lot to me and I don't see myself just abandoning it. They keep insisting I stop, even though I haven't wronged them otherwise. If I get thrown out, I'd have to cover tuition, rent, and food. I have a job but probably couldn't manage all expenses. There is a family I know who might take me in, but my conscience worries about burdening them and about hiding the situation. The biggest hurt would be losing my relationship with my parents and brothers. I don't know how long I can stay and pretend. I feel eventual discovery is likely, so staying might only postpone things. I also worry that hiding my faith is wrong. I've tried talking to them and explaining that being Muslim doesn't mean I don't care about family - in fact, my faith has helped me improve. They seem set on negative ideas about Muslims and don't accept that. Any practical advice on how to handle this? How do I balance my faith with keeping family ties? Should I try more dialogue, involve a trusted elder or local imam, prepare financially to move out, or something else? JazakAllahu khair for any thoughts.
