I agree with Rick. Not only are there people there who understand the difficulties of mental illness. It relieves you of the pressures of possibly having to disclose you problem to someone who can't identify/understand where you are comming from regarding your medical condition.
There is support offered there for those who our struggling, & I have actually met local people for coffee that I met on line; as well as, made new friends in other states that I speak with to offer support or just say hello.
As Rick said, FIRST RATE
