The problem is there is no clear blueprint for unconditional self love. People dont know what that is or how to do it. So they adopt narcissism as a subs because that is what is all around. It's easy to emulate.
I don't think a blueprint is needed. It is pretty simple: everyone knows what love is, and loving oneself is not much different from loving someone else. The only thing that prevents us from it is all the negative social conditioning telling us that we are not worthy of such noble feelings - but that conditioning is relatively easy to override, as long as one really wants it.
I get what youre saying. Social interaction is important but idk how to have friendships on a deep level where they call you guys hang out...
I do everything from being approachable to approaching and inviting people out and nothing happens. Idk what to do at this point.
Why do you think that people calling you to hang out means your friendship is on a deep level? We have regular office events, for example, when some of my officemates group up and go do something fun - but that hardly means that we are all good and deep friends. I would call us, at best, somewhat close acquaintances.
If your goal is to just be invited somewhere, then that's relatively easy: you ask people you know if they are going somewhere and tag along, and after a few times they get used to the idea of you being one of them and always invite you along.
But if you want to form deep connections with people, then that's an entirely different matter. For that, you must find someone you are comfortable around, someone you can open up completely and who is willing to open up to you. Such people don't just walk around everywhere, and it takes time to find even one person like that.
I have only one person (beside my parents) in my life to whom I am close enough that I can tell them absolutely anything about myself and expect understanding and acceptance. Some people, even very outgoing people, have none. You can't really force these things.
From my perspective, it is easy for us, less social, people to see those more social as having a lot of meaningful and deep relationships - but, in truth, what they mostly have is quantity, not quality. They have a ton of superficial connections with others, but even they are lucky if they have more than 1-2 really-really deep friends who will always have their back.
To me, what really defines a close friend is not who calls you to invite you to the dinner with their other 5 friends. To me, it is someone who, when everything in your life is falling apart, will extend their hand and go out of their way to help you. Someone may have 1000 "friends", but how many of them will go and sit with them in a hospital for a whole weekend if they get into a nasty car accident? Such people are hard to come by.
