Hello and welcome to Healthcare Magic. Thanks for your query.
Stress and anxiety
can manifest with not only psychological symptoms, but also with a variety of physical or somatic symptoms. However, a mole or an itchy skin lesion is a dermatological problem and is unlikely to be the direct result of stress. You will need a proper physical examination to determine the nature and cause of your skin lesion.
Irrespective of this, it appears that you are going through a lot of stress, and so, it would be worthwhile to seek professional help for the same. There are effective psychological therapies which can help you aquire better stress management
techniques and coping skills.
Wish you all the best.
