Whether or not what you're calling a "serious illness" is in fact a serious illness is a matter of opinion.
And you absolutely are telling people how to live their lives.
That doesn't sound like providing tools to me. Those are commands.It's almost summer, go out an enjoy being young. Gaming addiction is serious business. Take an extended break, or cut down your playtime, you won't be any less of a person for not having 4 subs at rank 40 for each main class by July. If you game all summer you will miss out on camping, biking, travelling/ road trips, swimming, tanning, going to the beach, bbqs etc, and all the other fun things life has to offer during any season.
