Two years as a stay at home dad, wife went back to work, totally different guy now

My wife got a job offer she couldn't pass up so we flipped things. I'm the one doing daycare, school pickups, cooking dinner, all of it. I miss my old job sometimes, the adult interaction and getting paid, but I wouldn't trade these years with my kids for anything. I know my kids on a level I never would have otherwise. But I also lost some of my identity I think. People don't ask me about my job, they ask me about the kids. When people ask what I do I feel weird saying stay at home parent. Some of my buddies from work kind of faded away. Getting back to the workforce next year kind of terrifies me because part of me likes this life better but also I need to feel like myself again.
