Changing clients

I am a new LPN. I graduated a year ago. I work LTC, and still do per diem. I wanted to try something new, so I am also doing home care. The problem is, I am having trouble finding my niche. I am doing one case, which I love, but it's only one day a week. I want to pick up one more. I have tried two, and neither was a good fit for me. One, because of the family dynamics, and the other was night shift, and I am not a daytime sleeper. Is it normal to "float" around in HH when you just start?? When I told my supervisor I didn't want the second client (and mind you I let them know after the first visit, because I don't want to string the family along thinking I am staying with the case) she said ,"It's ashame we oriented you, and you aren't staying." Shouldn't it be a good match???? Any experienced advise would be helpful. I am getting discouraged to continue HH. Thanks!
