Back around the turn of this century, I was VERY depressed. Enough to verbalize some suicidal-type feelings. Enough to want to stay in bed most of the day and not make the effort. Things got better after awhile, but all together, it had me down for about 4 years. Since that time, I can spot the signs better. Recognizing it goes a long way toward helping it pass faster. Right now, on a scale from 10 (everything's fine, couldn't be better) down to 0 (Slough of Despond), I'm probably around a 5-1/2.
