Tom, I think you are fantastic for posting and asking for information on this! I want to suggest that you remember that your anxiety/fear is not very realistic. It is not really fully true that you need to fear being alone, for example. Many people do well on their own and even enjoy it. I am not saying that you are being silly, because anxiety is a formidable enemy and you are dealing with it as well as possible. But it is not realistic to feel so much fear. I find that this thought helps me in my efforts to calm the fears. Best wishes!
