Is there a video interview to this?
Sounds like a real bitch if she left him because he lost his mass. Was for the better if so.
Sorry to hear about your friends brother. 23, damn.
With such an ordeal, you lose more than mass.
Im sure he was depressed as well, lost self-confidence, sense of self-worth, maybe even self-pity, didnt pay attention to the chick as much etc
There is a possibility it's not just due to superficial factors.
