This week's question comes from a listener who has a very difficult time being alone. 'When my girlfriend goes away on business trips,' he writes, 'I experience a ton of anxiety. And it isn't that I'm jealous of her - I'm I'm totally glad that she's having these experiences - but I get really anxious and my tendency is to want to immediately fill that space with with someone so that I don't have to have that negative feeling of being all alone, which I really hate. Is there something wrong with me?'
