I have a dilemma and need advice.....want your opinions

I am an oncology nurse (cancer nurse) have been for 13 years and absolutely love what I do. I have not decided if I like it better in the hospital or in the clinic setting but I love taking care of cancer patients. I am especially found of head and neck cancer patients and woman's cancer patients because I know the most about them. I was working in a big cancer hospital here in Ohio but had to drive an hour and a half to get to it on most days. So I started looking more local. I saw the hospital 15 minutes from my home had a cancer unit but at the time it was not hiring so I applied for a float position. A float position would allow me to work on several floors and when a space became available on the cancer floor I could transfer. After applying for the job I got a call. When the recruiter heard of my oncology experience she told me the oncology floor was hiring and I would be wonderful for that floor because of my years of oncology experience. I was so excited! I could work with the patients I love and be close to home! Win win for me! At least I thought! SO now I have quit the job at the cancer hospital and I am sorry to say burned that bridge because we were moving into this house so I took off my last two weeks. ( I know its bad and I should know better but I did it anyway) Turns out the floor I am working on is only an oncology floor in name. It is more of a cardiac unit! I do not like cardiac nursing. I am not good at it I know how the heart works and can read a strip somewhat but I do not like it I can not retain this information. I have to take and retake and retake cardiac classes! Actually it is a med/surg floor with cardiac and a hodge podge of other thing. That what med/surg is a hodge podge of everything. 

This is not what I want to do! I am a CANCER NURSE!! I love oncology nursing!!! But I still do not know anybody here! I have found some hospice nursing jobs in the same system and have thought of talking to someone about them. 
What would you do if you were recruited for a job because of your experience only to find it is nothing like it was made out to be........and you don't like it much???
