I understand the faking sick in order to get a break from everyday life. I've done it more times than I want to admit.

Try to remember that dynamics are a two way thing. If things between your son and you are not working, it's because of both parties…not just what you are doing/not doing. It's easy to blame ourselves and then feel like there is no use in trying. Try no to do this. Try to look at what you are doing or can do to make things better.
