Making Friends

How do I join other groups other than the main sharing circle and can I message people one on one who aren't listeners as well? I'm currently using the mobile app, not the website, but I can use the website if there's more options on there. I don't mind talking to listeners, but sometimes it's nice to have someone who relate on a personal level versus only comfort and advice, not sure if listeners offer that. I would still be talking to listeners, since that's what the app is for and I found the one I talked to helpful. But I also want to make new friends through this app to have someone to talk to and someone who can also talk to me about mental health issues that we share that we can kind of talk about our experience of slowly overcoming our issues and helping each other overcome them. I've had a few friendships like that and although it's not what the whole friendship is about, it's still helpful to have friends around who can relate and understand me when I'm going through a rough time without people looking scared or hopeless / sad they don't know how to help when sometimes all I need is someone to relate and understand. I also like being there for others as well, so I guess I'm looking for a friendship where we can relate and understand each other, with our mental health issues and get along regardless. But one way to do that, is to get to know people through group chats and one on one messaging. I just don't know how to do that or if it's an option. Or if that's an option with listeners if it's not an options with other users.
