Hi fellow newbie and welcome!
I feel your pain; I am in the down side of a depressive swing myself. Of course it always gets worse this time of year, but it is worse this year as I am separated from my son for the first time due to a recent divorce. So I know there are reasons, but I still feel the blackness welling up at the oddest times, when everything else seems to be going okay. But coming into these forums seems to help, so keep coming back to see us!
