facingus.org : has a wellness tracker, you can keep a journal here - useful
also samaritans.org : uk-based, can send email to "joe" (an anonymous volunteer) about your depression, and suicidal feelings. They email a compassionate, thoughtful response w/in 24 hours - I find they are professional and extremely empathetic and caring.

beyondblue - Home is another great resource (from Australia, but helpful anywhere)

also, Black Dog Tribe from the UK great place for fellow sufferers of mental illness to learn and communicate Black Dog Tribe
