Your title got me like, "Yea, Sure, lets do this", and I wasn't disappointed. Isolation does lead to suicide overtime and I quite agree with you on this that they (isolated people) often..

will tend to be easily offended because they have a low tolerance for criticism and frustration as a result of not having any experience of how social interactions are.

It is time we begin to reach out to all our loved ones, at least we don't if we'll be stopping a suicidal thought by this action, but we just might.
