Is it normal to not have permanent emotions towards people?
Ever since I was little I've had an inability with keeping emotions with my relationships. (platonic, romantic, etc) An easier way I usually explain it to people is I don't have object permanence with people. A few examples is my brothers have moved away and because they aren't near me, I don't give a crap about them really. My mother is in bed right now, I don't care about her. When I'm not hanging out with my friends, they aren't my friends anymore.
I genuinely wish this was different but I don't know whether or not it's normal or not, I can't help it at all I just have to fake it a majority of the time, like, for instance, one of my brothers came back home for Christmas last year and was really ill mentally, I genuinely pretended to care just like everyone else and I disgusting that I have to fake it.
I know that I come across as edgy but I just need to know if there are other people who are completely devoid of emotion towards people when they aren't there
