What broke me?

I was actually doing really well in independent practice and what has broken me and continues to break down my self confidence little by little is hospital patient care. My family medicine group does "hospital rounds" where basically one of the 7 of us looks after the practice's hospitalized patients each week. I hate it. I have been on hospital rounds for the last 3 weeks. 2 weeks of "mentored" time and this week on my own. I find it so stressful I really want to quit my job to not have to go back. Seriously. The worst thing is getting the 7-8am phonecall that someone has been admitted to your service. Now you have to go in and try to see all the patients PLUS do an admission in the 3-4 hours you have before having to go back to the office to see afternoon patients. Today my admission was a shit show. Not what was handed over, way more complex, a story that didn't add up, way outside my scope. I spent all day struggling with this patient and finally asked for an internal medicine consult from the run of his feet internist because it all just didn't add up. HOpefully he sees him this evening in the midst of his 100 other things he had to do. I am not an internist. I wasn't trained to be one. My internal medicine rotations were mostly spent trying to discharge patient who were admitted for failure to cope. I'm not sure how much I actually learned. I hate this.
