Need advice to give to sister

My sister turns 26 in 2 weeks, thus she will no longer be on our dad's insurance (he gets it through his job). She takes Xanax and can't just stop taking them because he body has a dependency now and she has seizures if she misses a day or two. I've been telling her for about 5 or so weeks now to apply Medicaid (I don't know much about it besides it's for low income people and considering she only makes $400 a month I think she'd qualify). I'm only 22 and don't know if there are other options for low income people since I don't have to worry about that for a few more years. Today she asked me if my boyfriend is on disability because she's trying to apply for it and told her no not yet, but I think applying for insurance is a little more important right now. She didn't reply. I don't know why she waited until two weeks until her 26th birthday to get her butt moving

**Edit

I don't like my sister much, but before y'all start calling her lazy, she isn't. She has multiple mental health issues that leave her unmotivated and doing something even as simple as taking a shower causes her to have a panic attack because she is so overwhelmed. While I agree she shouldve taken care of this already, she is not lazy
