Mounjaro- Depression

Has anyone experienced slight depression and anxiety after lowering the dosage. Do those side effects improve after getting off Mounjaro? I have never struggled with either issue prior to now. Wondering if it has something to do with my brain adjusting to lower dosages. Also interested if anyone has experienced cognitive decline as a result of the medication. I have been on it for 2 years. Lost 63lbs. Current weight is 116. I am on 2.5 (highest dose was 15). I have spent last year slowly reducing dosage.
