I'm an introvert who has a very extroverted job so by the end of the day I'm all talked out. I have 3 friends who call me and l talk to them. I can go days without talking and it's started to bother me now, at the ripe middle age of 35. Can you talk to some of the school mums maybe? Or try people watching in your local cafe? I know many mums who become friends that way too..it's hard, not impossible. You want someone who gets that you won't always be social so choose carefully. I'm married to a social butterfly so he gets his high from being the center of attention and I visibly crumble at the thought of a huge party/day out. I take a book everywhere so he just comes and finds me after his socializing and we go home. Find the friend who is like that - happy to coexist in your introversion.
