Why was my group deleted?

I created a group for people that have mental illnesses or loved ones with one. It was deleted? I see so many others and I feel like this topic is important to several people because it affects a large group of people. The audience makes a difference. People who don't understand or believe in mental illnesses will not be able to provide the best support. We're couples trying to have healthy relationships and families too. It makes a difference to not feel alone when going through something. It was nice to know I wasn't the only one trying to manage a relationship that is affected by mental illness. It's different and difficult. I'm not alone when I say that we'd like to see a group on here specifically for this need.
