I am usually a dependent but turn 26 at the end of the month, I have no income and need insurance soon. Can I file for medicaid even though I live at home?

I am 25 turning 26 at the end of the month. My parents usually claim me as a dependent because I eat their food and I live at their house. I have no income, but recieve SSI payments. I have already received a letter from my parents insurance saying I am kicked off the day after I turn 26. From my understanding I am not legally a dependant and they can't claim I am. I am trying to file for medicaid so that I have insurance but have a lot of questions. I called my state (VA)'s office and the person on the line said my dad's income will be counted against me. My parents can and will not pay for my insurance. Can I claim I am not a dependent but just live with them? What are my options? I would never lie or make a false claim, I just want to know how I can qualify for medicaid and continue living qt my parents house. Thanks
