For me its a good way to feel connected to my T. Feels better when I am going thru something hard and I can let her know what's going on. Very often she doesn't have time to reply but that is ok. I don't analyze the things she says or doesn't say. T often says things like "send me some emails" about whatever is going on if I won't see her for a few days, so she can keep updated on what's going on with me.
