This was the initial evaluation, but it is the English name used in Germany for dysthymia, which is long-term persistent depression, and has a low rate of remission (indeed they actually class remission as "has been given the mechanisms to cope with the illness" in the literature). Very few people recover from it, they just learn to live with it

The actual diagnosis was double depression, which is dysthymia ("permanent depression") + major depression (acute depression)
