I don’t do classes or anything but I’m continually socialising at home and out. I go to the cricket club every week and play on weekends all through the year. I’d agree that getting out there in structured environments can only be good for you. It forces you to think in certain ways that help your social skills.
Social skills can be learned and that means practice! It’s easy to isolate with schizophrenia but to have some success sometimes you’ve just got to open yourself up to different experiences…whether with family, friends or strangers…just getting out there!
