Anyone new that comes into my life, even if they become my “friends” or hell, even a girlfriend, I couldn’t care less about them and don’t value them. If they have kids, I don’t care about their well-being either. Basically I could not give less of a fuck about anyone. I don’t care about my friends or family members at all. If they are sick, I don’t care; if they die, I don’t care. It’s not even that I don’t “like” them; it’s more apathy than anything else. Don’t care whether they live or die. They don’t care about their children or their well-being. Here are my “emotions” towards people. I either tolerate you, or I’m purely apathetic. Or I just straight up don’t like you.
But I’m going to be in more social situations around people I hang out with – friends, family, etc. – and I need to fake like I care about them.
How do I do that?
Seriously, get help. Detachment like that usually means something is quite severely wrong. Could be depression, could be something worse, but regardless, this is not a healthy state to be in.
Therapy / counselling, there is usually a reason for this kind of detatchment
Seek professional help before somebody dies.
I don’t think you can or that it’s even wise. I think therapy can help you mitigate consequences, and if you value these people in any way, you will make every effort of going to a therapist, being honest, and participating to make the situation more tolerable for yourself and potentially others.
Get help
I don’t think it would be useful or even possible for you to fake that. I get that when you don’t care about things you probably don’t care about solutions that don’t just mitigate consequences either, but I think it would be smart to seek professional help and get over this in a meaningful way. I don’t think you are fundamentally broken in any way but it does sound like you have some stuff to sort out and therapy would probably help a lot in that.
You don’t need to fake liking anyone.
Just be yourself and if they don’t like you, who cares?
