<p>Jym–thanks for that link. The article doesn’t, however, address the role of mental illness in suicide. In my brother’s case, I would say that mental illness could be substituted for the “thwarted belongingness” circle on the Venn diagram. He certainly had the other two pieces–capability for suicide (ready access to guns, life-long hunter) and the perceived burdensomeness (which stemmed from the mental illness). He did not seem to feel alone, and had many connections through family, work, church, and friends.</p>
