I live alone and talk to myself too. My parents always wanted me to live alone after being hospitalized. I don't know the reason. I've gotten used to living alone and do everything on my own. It is difficult to be alone. You have to do everything from paying bills to taking care of your place. It is not easy. However, I like my freedom but it comes at a cost. The cost is that when you need help, you have to ask others in your family or make friends who can help you which I have not been able to yet. Besides this, life is manageable and ok.
