before I was integrated the first thing I did was contact my treatment providers. by doing this my doctor, therapist and psychiatrist were aware that I was in active depression..

from there ...

my doctor would do a physical to make sure the situation was / was not a medical issue...there are many medical and normal issues that caused me to be depressed and not know why...lack of sleep, poor diet, not enough fluids....

my psychiatrist would make adjustments to my medications because sometimes I would develop a tolerance for the medication or the medication dosage or kind was too much or not enough or wrong meds now...

my therapist and I would talk about things like when does this feeling hit me, what does it feel like mentally and physically, whats going on in my home life, whats going on in my love life,.....

eventually the reason behind the feeling depressed would show itself.

in the mean time my treatment providers and I would set up contracts / emergency plans just in case they were needed should the depression slip into self injury or suicidal thoughts/plans/actions.

On rare occasions my feeling depressed for no reason would turn out to be my becoming co conscious of an alter that was depressed. in these situations my therapist and I would talk about the same things as above and she would have me do whats called...sit with the feeling...which was allow myself to feel it/write about it/ draw it/ and other ways of expressing it...over all we considered my being able to feel an alters depression as a good thing because it showed I was healing enough to be able to handle the feeling of depression on my own with out having the alter hold that emotion/feeling away from me. sometimes my therapist and I would sit together with me wrapped up in a soft blanket and my therapist holding me while I let myself feel that depression and cry if the need be.
