Friend at work making things worse for me?

One of my best friends are I work in the same company. She has no sense of time or deadlines but it never becomes evident to others because she is good at communication and pretending that she does a lot of work and has a lot of ideas. She is a wonderful person otherwise but lazy AF at work. I try to cut her some slack and cover things for her but this is now affecting my mental health because it looks like she is taking me for granted and continues to not complete tasks on time and never honor her words. I hate chasing her for basic tasks. She really crossed the line a few weeks ago and was straightup disrespectful to me. I have since set some boundaries but I shudder at the thought of having to work closely with her. What would you have done?
