My friend is making my life hard

I’m really just complaining because I know This is temporary.....

But anyway some background here:

I start a new job in the morning

My friend just got broken up with today

She lives an hour away from me

My friend has been with this girl 3 years and after they broke up she asked if I can stay with her for a few days. I said yes, when I’m available. I don’t feel comfortable calling out of work on my first day and they’re going to give me my first schedule in the morning so for now I don’t really know when I’m free.

On top of that I share a car with my fiancé who also works and needs the car mon-fri so I would need her to come pick me up or have my fiancé drop me off when available which is awful for either of them honestly especially since my fiance works 3rd shift.

So I told my friend that until tomorrow after work I wouldn’t know when I’d be able to stop everything and come visit her. She’s pretty upset with me because she really needs the attention and support. She could stay at my place since she doesn’t work but she doesn’t want to.

I don’t mean to be upset but ive had to put so much of my life on hold to help her for the past two weeks as I’ve witnessed the falling of her relationship. I haven’t been able to spend time with my fiancé, I haven’t gotten much sleep when I had things to do the next day, ive been answering her calls at all hours of the day and night and talking for around 2 hours each time trying to help her. I haven’t had much time to clean my house, make doctors appointments for my disabled sister, pay attention to the things I need for my new job, spend time with my fiancé, make dinner, or literally anything else you can think of. It’s very taxing... I’ve put so much genuine effort into helping her at the drop of a hat when she needed it and now she’s mad because for the first time within this time I don’t have a choice to visit her and cater to her. I literally can’t help this!!!

I love her to death and of course I want to be there for her but I’m so so tired and I want to cry thinking about how she’s upset at me because I have to work... I mean I didn’t even sleep the night before orientation because of her and I didn’t complain once! I guess I feel under appreciated
