I have a friend who has no interest in literally anything at all-except investing and earning passive income-as he puts it himself. Multiple times, I tried to bring him out of his comfort zone, ie. playing games like Town of salem, and zelda breath of the wild but he found it complicated and gave up entirely. Shopping, or hanging out at events, parties or exhibitions does not seem to interest him. I think he is a bit agoraphobic too as he feels uncomfortable if he travels too far away from home and gets a panic attack. Recently, I shared some links about anhedonia and avolition. I told him it's probably part of the illness because he has complained that he is bored multiple times but made few attempts to make his life more interesting. 

I also feel like schizophrenia has links to autism because he doesn't see the importance of dressing well if he wants to snag a girlfriend etc. I am not sure whether he understands personal space, or boundaries that well, or like social trends: ie. nowadays, people prefer to text or meet face-to-face, and potential gfs may not want to call him and talk on the phone with him. 

I have tried many times not to hurt his feelings, tbh he finds his social skills average but for a socially awkward person like me, I find them somewhat lacking tbh. Today we were discussing our personalities and how I am outgoing and I seek attention and validation from a lot of people(diff disorder/personality type) while he's so different from me. 

I've been diagnosed with schizotypal before, but sometimes I think I am more on the hpd/npd/bpd spectrum, and I was trying to explain how I constantly seek attention and validation from lots of people, even strangers while he has a few close friends.

Like I don't wish to offend anyone, but I am not sure whether schizophrenia has affected his base personality somewhat, or his love of routine was a in-born trait. I feel like I have read a study about how people with autism/schizo traits such as a need for routine, preoccupation with one or two things-&gt;may lead to full-blown schizophrenia.
