I understand it on a surface level. I can generally pick out behaviours of depressed people. I can even recognise when someone is depressed a lot of the time. I understand the google meaning of it BUT I just don't understand how someone can have it. Obviously no shade at anyone who is dealing with these types of problems, I'm not going to be that person who says it doesn't exist because it very obviously does. But i just don't understand it, why can't people just change their outlook? Why can't people just not be depressed?
