<human>: Can you give me the gist of the text in a nutshell?

My friend lets call him John,has for quite a long while been fed up with relationships with girls and people in general. This is due to his experiances in the past and his opinion that he has no hope left for that part of his life. 

When people tell him to be positive or get over it he just gets angry and withdraws more from others.

He has said that "it feels like something is there but nothing is at the same time"  He also refuses to seek physiatric help as he doesn't have the money and doesn't feel like he could open to a stranger. 

What do I do,I fear for his safety and mental well being and am scared that he could harm himself physically if he continues down this path without intervention.
