^^ That is cool, but it really needs to be on the page of the group.
Right now your group is just a blank page, I recommend adding more to it so people have a reason to join, an icon would help to.
I'm going to decline your offer at being an admin, through bad experience with other groups, I don't join group where it appears the founder wants the other admins to do all the work. These groups look very bare like yours does so far.
Some advice.
Maybe requests works around anxiety, depression atc into the group.
Maybe a journal containing various helplines from people to call.
Gather a collection of badges for people to use.
Affiliate with groups just like yours, you might find some useful tips on their pages or from their members.
