New here struggling with aggressive defiant 17 year old boy with gaming addiction

 Q1, Do You or others believe your young man is autistic, does he has other signs visible to you and others. They are well documented, and some of the ablest discus their problems etc on this website.

While playing endless games in a make believe world is used by Autistic and non autistic children and adults to escape into a world they may feel at ease with, being able to cope with the game, as it does not need any specific education (Unless it is Educational in some way).

Q2. do these games he plays cost him money for credits, or does he have access to your credit Cards, or forces you by flare ups to pay money for his games.  If So He is a Gambling Addict, or fast becoming one and really needs specialist help. 

Unfortunately a lot of today's "Games" are designed to be addictive and never ending.

 The fact that he has not attended school for 5 years must mean that your son and you have been failed by the State, your previous Local Council if resident in the UK, and another Council continues to do so.

I can only suggest that you go to your CAB office and seek help. Your MP should be made aware of how the State and your has failed you and your family. Keep a diary of who you speak to, what is discussed, Names of People, etc.

To me it is highly probable that your son is autistic and the State/Council has failed him. especially those connected with Children as they have classified him as an adult to escape their responsibilities for children.

Please see also your GP as your son needs help from somebody.
