I am having disorganized thoughts. for example my internal thought process will go "finish typing this sentence cardboard sweater". what could this be?

Talk about it in Tx: It is probably frightening, but it can be a less terrible Dx than psychosis. Describe it in accurate detail to your therapist. If they think it is something you can work on, that's good if not ask for a referral. Eval and Tx plan is what you need. Whatever it is, you'll be able to start to deal with it. Don't give up and try to feel strong. Then you can meet this challenge. Best!
