I honestly believe the truth is important. You could tell your pdoc that you can cope fairly well and are at a low risk, but that you are having htese thoughts anyway. Your pdoc may be able to help you safeguard yourself without much longer therapy. With depression, these thoughs can come and go and it's your therapist's task to teach you copign skills, not to wave a magic wand and hten the thoughts are gone. For this reason, I don't see why sui thoughts mean you need more therapy per se.
