Anxiety Disorder and irritable bowel syndrome?

please read and be serious.. im 28 male with gad and have notice over the past years with my anxiety disorder that i feel frequent urge to urinate and discomfort almost like uti and get little pricks of pain in groin and pelvic area.. is there a link to ibs and anxiety here are my symptoms.. i get cramps and pain in groin/pelvice area, increased gas and straining farts and bowel movements feels better or relieved after i go to urinate or have bowel movement. my stools change and is constipated in morning not all mornings but most. some foods i eat make my stomach bloated and naseau. with my disorder i always think the worse like bladder cancer or some serious illness. i notice i pass gas more than i used too. i have had urine test and blood work done every 6 months and said all normal if it is normal why do i get pains and discomfort?
