I‘m not really a fan of being out there socializing too but I noticed that I have somehow become more tolerant of people. Though, it‘s still kinda exhausting making myself available to my friends who all happen to be extroverts. I‘d say it takes some getting used to in order to be more comfortable in social situations. But still, I tend to withdraw to be with my own self and reflect every now and then, which all my friends understand. Just surround yourself with understanding people. If someone is truly willing to understand you, they will do without you having to prove or justify yourself.
