Mistake Switching Jobs

After working in an outpatient setting for 4 years, I began to miss working at the bedside. Recently, I returned to the bedside working on a medical unit. While I'm enjoying caring for a variety of patients, I'm feeling like I've made a mistake returning to this setting. I knew what I was getting myself into, but now the reality has set in. I'm currently on orientation and trying to decide to stick it out for a year and transfer or apply for jobs while working.Has anyone been in a similar situation before? I feel so guilty for feeling this way.
