This is some of my experience with depression.
I feel a heaviness in my heart/chest - not a physical heaviness, but emotional.
I feel on the verge of tears most of the time, although since I have been on anti-depressants I don't cry very much.
I would rather lie in bed than doing anything else, although I can and do force myself to get up and about with my daily activities.
I don't enjoy anything - even the stuff that's supposed to be fun.
I don't look forward to anything.
I feel hopeless about the future.
I have no confidence and feel incapable of doing anything right.

Not sure if this helps at all or if it is the info you were looking for. I agree with gimmeice, everyone's experience is different, and the journal thing is a really good idea.
