My friend thought I didn't care about her, so ended the friendship. What should I do?

My friend said she felt neglected by me and it was hurting her. So she ended the friendship. I didn't mean to make her feel neglected, I was really busy at the time. What should I do? She won't even watch my stories or engage with me anymore.
