Working From Home Isolation

I've been freelancing from home for about six months now. The isolation can be intense; I hardly see anyone outside of my immediate family. Today, while on a call with a client, I found myself staring at their background photo, a beautiful beach, and suddenly felt an overwhelming urge to just run away and visit someplace far, anywhere but here. Am I the only one who feels this way? Is it normal to experience such intense cabin fever despite liking the flexibility of remote work?
