I’m obviously mentally ill:  

• 15. 
• Since start of 2019 (maybe dysthymia?). 
• I manifest stoic behaviour; I have barely any emotion. 
• No environmental cause; a natural illness. • I’m anhedonic. 
• I’m a sadist - I indulge in watching a lot abnormal videos which most find ‘disturbing’ 
• I have extremely severe anti-social behaviour. 
• not another edgy teenager since it would be illogical to continue a facade for two years when I have responsibilities to take care of and school exams. 
• ridiculously high grades - I ace half my tests because of my ravenous attitude towards studying even though I hate it.  

But does anyone know the mental illness? Or is it a combination of multiple things? I can’t find anything which fits the description.
