Is a typical mental illness support group focused on only one type of mental illness?

I am trying to write a story about a lot of characters, all suffering from different mental illnesses, who meet and become close through a support group. I used to have an eating disorder and I would go to a support group for people with eating disorders. And I know there are support groups for people with anxiety, etc. But would it be realistic and plausible for many different people with many different ailments to all be at the same support group?

Thanks!

I've seen anxiety/depression groups, because they're often comorbid, but not general "mental illness" groups. (It could be possible, though. Do a little research in your community to see.) I suggest the people have one thing in common (such as an addiction, adult children of alcoholics, or anxiety), and their own unique issues as well. that would be very realistic.

If you're thinking of 12-step groups, they tend to be one-issue-only (Alcoholics Anonymous, Overeaters Anonymous, Sex Addicts Anonymous, Gamblers Anonymous, Marijuana Anonymous, Nicotine Anonymous, etc.).

Those aren't the only types of self-help groups, of course, but that's one type, and they do tend to be separate groups for separate problems.
