This is Dr. David
do you have excessive anxiety symptoms?
excessive anxiety can cause you to feel itchy and scratching can make it worse.
I am sorry you have been having increased stress.
any rash on your skin?
any need for you to upload a photo of your itchy skin?
did you have any other problems with anxiety or itchy skin prior to this 6 month period of time?
have you used moisturizer after your showers daily to help calm down and moisturize your skin?
have you tried any calming cream like calendula creams? these could help.
do you think you would benefit from seeing a psychotherapist to help you stop scratching.
