Good day . I can understand your concern and desperation to come of this pain. Our body and mind are closely interconnected and any emotional disturbances like anxiety or stress can easily affect the physical functions of body. In Ayurveda terms, anxiety in mind can increase vata or air energy in the body. This air energy imbalance causes drynesss in body which in turn dries up stools to causes constipation. Such problems needs a holistic approach of balancing both body and mind through therapies, few lifestylechanges, dietary and mindsetschanges. . Be positive.  It's an addressable symptom. I am also an Ayurveda wellness counselor and Varmam Therapist.  There are natural and alternative solutions available.  Feel free to reach me for further assistance Be positive. You will be alright soon.
