When I was having extreme anxiety due (at the time) to an undiagnosed medical condition, googling my symptoms contributed an extraordinary amount to my anxiety - so much so that the doctor who finally diagnosed me banned me from googling anything about my condition or going on the message board for that particular condition. It was the best advice I got. She also suggested I go back on Zoloft - which I had been on several years before, but went off when the stressor at the time was eliminated.
While not the only answer to the OP’s issues - curtailing consumption of those things which are obviously contributing to her feelings of dread may help and certainly will not hurt her.
Exercise is also a useful tool as it increases endorphins. Yoga can reduce stress by quieting the mind and relaxing the body so one is less tense. Once my instructor starts talking my mind immediately stops wandering and I think of nothing but the yoga for the whole class.
