Feelings of guilt, worthlessness, helplessness
You may think that it’s your own personal failing, that it’s your fault that you aren’t happier or more productive. The fact is that those feelings are direct symptoms of the illness.
“You just have a sense of worthlessness. You tell yourself that everything that you are doing is wrong, that there’s no possibility of succeeding. If you’re looking at changing your life, you won’t because you know you are going to fail and you just reinforce that self-fulfilling prophecy. So you don’t even bother telling yourself anymore.”
