Hi Rift, you haven't said if you see a psychiatrist or not but it sounds like depression alright. Maybe a change in medication or beginning a medication would help bring you out of the dark place. I sure can relate to what you said because I've been in that painful dark place too many times. Medication has helped me.
Hydrosloth, Welcome to the group. You describe the way I felt before I went for help at a county mental health clinic. I was 7 yrs sober and I was tired of dealing with depressions that seemed to come out of nowhere. Have you been seeing a mental health professional? I hope you feel better soon.
