You are who you are. If coding makes you happier, make time in your life for it. You have acquired the knowledge and experience (skills) to be social. Sometimes you don't have to listen to the criticism you hear (especially if it is coming from your own thoughts)

I hang around with a diverse group of friends. I find that the more interests I pursue (improv comedy, entrepreneurship, triathlons) the more people you meet. Some of them shape your life view; others are merely acquaintances. I am always shocked to learn again that some people don't think obsessively and analyze everything (a.k.a. analysis paralysis née nice guy née loner). One positive aspect of being able to dive into coding is that you can always exercise your creative mind and feel good, without relying on other people.

Life is not a measure of its longevity, but its complexity.
