My cousin texts too much and she always thinks something is wrong if I don’t respond and it drains me what should I do?

She lives in another country 5 hours behind me and she tends to text every single day all day long. She in her 40s and keeps asking if there is something wrong if she doesn’t hear from me for a few days but I don’t want to text 24/7 I’d rather have days just living life getting things done like work, gym etc
