What are signs Emotionally draining friend /roommate?

My friend has lived with me the past two years and it’s been a really hard on friendship in my option. I understand that everyone goes through rough patches but it seems like every week of day something bad is happening to her or her family. She is very emotionally draining and if I ever have something wrong and want to talk to her she always does this deep sigh and then is like ok what’s up and when we I talk to her she is always on her phone and barley paying attention it’s really starting to hurt and I have said something and she somehow makes it my fault. I’m not saying that I am perfect or haven’t done anything to upset I’m sure I have but I’m just exhausted. I feel like I can’t talk to her. also she never cleans up after her self I have tired everything to get her to I’m feeling used by her.
