mentalhealthforum.net would be a valuable resource.

I’m trying to start a group called Life Support. The idea was born from me sitting at home for weeks without a call from family or friends. When you’re depressed, you don’t always want to call someone and bring them down. So, on the basic level of the group, it would provide names and numbers of people in the group (willing to share those numbers) who have some understanding of what each other are going through. We would all check up on each other and also have someone to call before doing any harm to oneself. It is also to have get togethers or outings, game night, movie night, classes on whatever people would like, sharing and teaching of talents, mentorships for business, giving talks to schools, creating a book of poetry and artwork, doing podcasts and more.
You could start your own version of this.
