I don't know that I have misjudged someone when they were at their lowest point, however, the opposite has been done to me. I used to completely hide my feelings, so even when I was in a state where I was basically walking dead, people thought I was fine. I couldn't cover up a lot of the problems the depression and suicidal thoughts caused though, and a lot of people judged me for my mistakes, saying that I was just being lazy. I couldn't tell them why I really was acting that way, So I just accepted the label, telling myself I was stupid and lazy, that I would never amount to anything. There was a constant inner battle going on in my head, whether I should listen to the many people, my family included, that were telling me I was worthless, and never would be anything more, or whether I should listen to the few people that said the opposite. Luckily I listened to the latter, and have since built up a strong support system. Now I try not to judge people, until I know enough to accurately do so. I know that if I misjudged somebody like people misjudged me, that person may not be as strong as me.. and may end up dead because of my words.
