Please do remember that schizophrenia is a brain disorder in which many higher mental functions such as decision making, logical thinking and even memory and attention are variably impaired. If your son fell ill at age 15 he really had no chance to go through the experiences that normal people go through and which help them in decision making later on in life. Right now your choices may not be too extensive, but do make full use of whatever facilities you do have. Just because his disability is not visible, does not mean he is any less impaired than say a mentally retarded child.
