It is going to be ok! I have not been diagnosed myself but I know the devastating feeling of getting the diagnosis for a loved one. The unknown and uncertainty can be overwhelming. Start with early intervention therapies. Find support groups such as the Agenesis of the Corpus Callosum Facebook pages. Doctors can give a negative outlook on things sometimes. Don't listen to it if they do. They cannot predict everything and more times than not, people with this condition or others, prove them wrong repeatedly. Try and stay positive as hard as it may seem, find those support groups and reach out to others. Knowing you are not alone in this can be the most useful tool.
