The whole point of meditating is, among other things, to kill your ego and stop being selfish. You may meditate for other reasons and that's okay, but if you happen to be interested in becoming more social, consider thinking more about other people instead.
I've been antisocial since literally forever but I am starting to feel like I am changing in that regard now that I'm doing this. Specifically, I like to think about how to make them happy, what kind of thing they enjoy doing and how I can help or accompany them to do it. I also think about their problems and worries and deal with them as if they were my own, and I let them know that I worry about them. And most importantly, I never judge them and when I see that they are not confortable with me I accept it and move on instead of forcing a relationship by fixing whatever they don't like about me, because if their happiness matter that much and they are more happy without me, moving on and let them go with their own life becomes a no-brainer.
I am sharing this here because I think there is a very subtle relationship between this and meditation. When I started meditating, after a while I started noticing some kind of emptyness inside myself, but a positive one. I think this is what killing your ego looks like, in a sense that I didn't care about who I was in the same way that I used to. Emptying my mind felt so unnatural, so against what made me myself because I have always been an overthinker with some ADHD. It felt as if I was destroying a very important part of myself because it was destroying me, and then you sense this positive emptiness inside yourself because that part of you is not there anymore. And now that I see social relationships so differently I am starting to feel in a similar way. I couldn't have cared less about other people. Seriously, why would I even bother if I am happy with my life already? But every time I make an effort to talk to them to make sure they are okay, every time I do something I know they will appreciate even though I normally wouldn't bother, I feel like I am destroying my own identity. But by doing that, I also feel like I am becoming someone else, someone who just makes more sense to be.
