I can’t concentrate and my grades have gone down/My boss has noticed I’m not able to work productively

Disorganised thought or inability to complete a task

Jumbled and confusing thoughts, or not being able to hold a clear train of thought. This can make your speech come out as rushed, random and confusing to those listening (such as switching from one unrelated topic to another in mid-sentence). If you have disorganised thinking you might often lose your train of those, leading you to frequently and abruptly stop speaking whilst saying something or to abruptly stop an activity with difficulty remembering what you were saying or doing.
