The past year or so I've been more active with my local Baha'i Community and a local church. I make it a plan to have dinner with a friend or a group of friends at least twice a month. I call my relatives and other friends on the phone more frequently and often talk for an hour or more. I try to go to special events, whether they're art exhibits, sporting events, or what have you whenever I have the time and the money. Most importantly, I try to get Dala involved in things whenever possible and when it's not possible, I be sure to do things with her one on one, even if it just means sitting on the couch for an afternoon reading while our dog sits between us.
All of this has made an immense difference in my mental health and world view and every single day I find myself waiting anxiously for the next time I can get out of the house and interact with people. In fact yesterday I found myself feeling a bit melancholy just because I went to such an amazing picnic over the weekend that I think I was crashing from a bit of a high.
There's a whole world out there people and it's fucking amazing. Gather your family, gather your friends, and go explore it. You don't know what you're missing.
