Welcome to HCM
We understand your concerns
I went through your problem description. Your friend is in need of psychiatric help. He is acting strange and could be because of attention seeking personality disorder
or schizophreni. Before concluding what problem he has, we need to analyze all the symptoms he has and analyze his life style patterns and behavior aspect. Convince your friend to co operate and visit a psychiatrist
Hope this clears your query. Available for further clarifications.
