My boyfriends son suffers from depression and anxiety.? He NEVER has eaten fruits or vegetables doesn't drink juice and does not take any vitamin supplements. He is 9 years old. They want to treat him with medication but I believe it is caused by lack of the proper nutrients.  He always has stomachaches and does not want to go anywhere or do anything and has no friends. I have watched this develop for the past 4 years, getting worse by the day.  What advice can I offer.  I've tried to feed him fruits and veggies but he won't eat them.  He is also slow with his hand coordination and his speech sounds like a 4 year old.  What can I do.  This has affected everyone around him.  We are all stressed.  We have become prisoners to how HE feels.  What can we do?

Summarized question: What should I do if 4 years old suffers from depression and anxiety and does not take fruit and vegetable in diet?
