Or were you in the recent past?

I've been in therapy for a number of years. It helps with some areas of my life, but it's not helping with depression, which has gotten much worse. It seems like the longer i have it, the worse it gets.

I hardly read posts about depression here, so i was wondering how people are helped by therapy with depression. Depression as in clinical major depression (as opposed to being lonely, not living a full life, relational problems, social anxiety, etc, or one aspect of life. Depression as in cognitive problems, under/over eating, under/over sleeping, lack of enjoyment/interest, no motivation, hopelessness, spending hours in bed, etc.

I think some components of my depression are psychological, and i have a childhood history trauma, but i wonder sometimes how much of this is more related to physical problems such as the effect of years of stress, including hormonal imbalance. I feel like i have brain damage. Alcohol and drug addiction also runs in my family, so i think there are some physical components to that as well. Like it seems there are endorphins missing from my brain.

So, I'm trying to pull myself out of this and feel so incredibly hopeless and it's making me feel worse because i get overwhelmed and start thinking-why even try when keep failing? I am wondering how therapy helps or has helped, or even things that you have done for yourself that have pulled you out of depression.
