I find blogging; writing my feelings, thoughts, and issues down, not necessarily sharing them with others, but letting them 'out' in a place where I won't be judged by my nearest and dearest, is extremely therapeutic.
It can be surprisingly relaxing to express any anger or sadness, or negative energy, through words via a relatively neutral medium.
Isn't there a saying that you're confident in a room full of strangers, but with those closest to you, you become a shy mute.
Perhaps it says more about the individual, but I personally find blogging an aid during periods of stress.
