I like being alone. I'm good at being alone. I was an only child, often left alone , and I have lived alone (although dated a lot) for 20 years. But if you put me in OPs situation, it would easily be tough. Working from home, living alone, totally lost your social circle possibly, AND sad over a recent breakup probably. Thats a prime recipe for problems even for people that do enjoy being alone for the most part.
