If you are digging up some pain in your past that's fine, do it, but beware of psycho-archeology. Don't keep digging for gold in an empty tomb. I've seen therapists keep people crying for months digging up their past, picking at the same things repeatedly. There's a time to dig and a time to put the shovel down and bask in the sunlight, thankful there is work to do, and problems--that really aren't that bad.
