Same as you op. But contrarily to you I know why I get these.
First off, except the 1% of mental ill people, you biologically CRAVE social relations. That is true for 99% of people, even most autistic for example. Why? Simple, humans CANNOT survive alone. Don't send me example of people who tried to survive for a limited period of time. Most humans are just unable to survive alone. Humans thrive in groups. That's why social interactions are almost as important as food or sex because they are an IMPERATIVE to our survival as individuals and as a specie.
The fact that you have no or little social interaction will often; like a lack of food will, create a real craving.
Now I'm going to take a bit about myself and some including you, op, might identify in what I will say.
I have been rejected pratically all my life. My parents hardly gave me actual attention past 5yo except to tell me to have good grades at school (which I did not because of bullying). Adults sometimes gave some but I always got rejected by people my age. I mentionned bullying and that happened to me until high school where I hit a late puberty and was (finally) able to fend for myself, because NO ONE ever tried to protect me, even teachers participated in it.
Now the thing is, I have a very friendly personality. That means that I always (even know sadly) see the best in people and try to befriend them. I tried during all my school years to make friends and at some point I even got mocked for that. I tried outside of school but it never worked. And as I was growing older and older I was becoming gradually more desperate to have friends. Ironically, it's harder and harder to make friends as you age and around 25, my age, it's basically impossible to make friendships since people already have a social circle and will not make a new friends from the spot, they will usually make new relations from their social circle. If you have no friends, it's impossible to make new ones. It's a true viscious circle.
And as you can guess my craving only intensified as I got ignored, bullied, rejected. So that explains why I absolutely crave, even after YEARS as a NEET (over 5 years now).
That's a bit sad since I KNOW that even without the rejection, I always wanted to have friends. But I will never have any.
