It looks like depression
to me but since you have had it before, you may be the best just to decide weather it is depression or not.
But, the label is not as important as the problems, is it not?
For the moment you are having symptoms which occur most commonly together in this label called as depression but even if the label is not given to you, these symptoms will respond to talking therapies or medication the same way when they are lumped together in a label.
So, from their response to treatment point of view or your need of treatment point of view, what is important is how much are these affecting you? Obviously significant enough for you to seek help/advice online.
So please go see a psychiatrist
. Even if the label is a different one like ""prolonged grief" or "adjustment disorder
of depressed type" or "acute stress
reaction" or whatever mumbo jumbo we label it as, the bottomline is weather you feel the need for treatment/help now or not.
I hope I have not confused you too much :-)
