I agree with Yumi. Give her space then. I know it's tearing you up inside, but give her as much time as she needs. Some weeks ago, I asked my Mom to stop calling and emailing me. I was going through a depressive episode and needed some alone time. I know it tore her up inside, but I needed a chance to breathe and sort out my thoughts. As soon as I was ready, I started emailing her again. We've never had the best relationship, but asking her to back off didn't mean I didn't love her. Your daughter will reach out when she's ready.
