I was thinking of a book club too. There is a website called meetups and I believe they have religious groups you can join. If you have any hobbies, there are forums to get more involved or local groups sometimes. Take a class at a local community college or adult school if you have any in your area. Increasing social health is important in long lasting health, so I applaud your desires and efforts to get out there.

Welcome back to the world. Winter depression is horrible. I hope you find something soon and stay out of that dark place.
