What should i do

Am so fed up and I do not know what to do. People are so ungrateful.am not so good talking about my friends but it's too much. My friend had problems she just broke up with her husband and she needed a job and a place to stay. I told her to start working in my shop and I also got her a place to stay. But what really breaks my heart is this lady has forgotten her problems and how I helped her. I wake-up early in morning at 6am and go to town shopping but Tue lady opens the shop at 10am yet we have to open the shop at 8am and some clients call me early in morning when need clothes. And she opens up so late and she is always sleeping. I come back at the shop after shopping I find her sleeping and she can sleep the whole day. I have tired so hard to talk to her but she doesn't change. What should I really do because am thinking of telling her to look for a job somewhere else. I need advice
