I am introverted as well but I have not been able to get much motivated into getting into group activities with a lot of friends at once, or especially strangers. And never having a SO or a serious relationship in my life, now being age 36 probably is affected by that. I don't live alone right now- I live with my mom for financial hardship reasons- but I usually keep to myself.
