You will be surprised at how much help, support and information you may receive from them. Even if other members have children with different needs than yours, you will find many common topics to discuss. Check your library or online for national organizations that deal with your child's disability. Often, they offer support for parents through conventions, workshops and publications. There are online groups and listservs that deal with virtually every disability.
People are only too willing to share their experiences and offer advice, tips and resources.
Support can come in many forms and help you in ways you don't expect. Take time out for yourself. Even if you feel pressed for time, you need to carve out time to focus on yourself. Set aside your daily chores or work for a little while. Take an hour once a day or even once a week and do something just for you.
