Personally I've had moments of horrible depression and doom where I'd be in my room crying and bemoaning my situation to a near paralyzed state. One instance had lasted around a week, of which I had prayed and expressed my feelings and issues. I suddenly had an overwhelming sense of calm and started telling myself what I needed to hear and within about 30 minutes I felt like I had a 180 on every thing bringing me down. Maybe it was just my chemicals came back in balance but it doesn't disqualify the possibility of some external help.
Also our living condition borders on evicted and living comfortably so closely it feels like someone is giving us the slightest help sometimes, though I do know my family works hard to keep things going, myself included
