Ha Ha! reading back on this post. The stress took its toll and I was diagnosed with cancer soon after this.. All is good now, my son still plays his games going to college but turned out to be quite self sufficient, happy and lovely individual. He has recently been offered a place in a top Uni. Thanks for your comment.
Sounds like depression and anxiety,but a doctor or therapist would be able to diagnose him.This situation reallly appears to be affecting you aswell,it might not hurt for you to get some therapy aswell to see if you can relieve your stress and anxiety as a result of your sons behaviour.I wish both of you all the best.
