Leaving but not started yet

HI everyone, I'm just asking for some advice. I'm about to qualify as an RN in the summer, and need to start applying for jobs soon. The only thing is, I'm really not sure if it's the career I want anymore, I don't know if it's just pre-qualifying nerves or if I really don't like nursing. Has anyone else felt like this?
My student friends are all applying for jobs and looking forward to qualifying, but I just keep on feeling as if I don't really want to do nursing. Would appreciate your help on this.
