Unable To Verbally Express Instructions Even Though The Though Is

Unable to verbally express instructions even though the though is in my mind just can't express it to where others can understand. Jump subjects in explanations and also leave parts of a sentence out when writing. Even when all the words are mentally being said. This has worsened over the last few years. Like the statement is being rehearsed in my head but I may leave out major parts of the statement. I have always had difficulty following written instructions to preform task. Have some depth preseption. Have in the last year losing amount of time to preform normal tasks, and shopping the time looking for a certain item not realizing that it is extremely amount of time. Visually hard to pick out and find certain objects in cluttered areas.
