I know this might be a silly question. lately, i have had extreme anxiety when it comes to my health, but could things like herpes be passed by just talking to someone? you would need to have direct skin-to-skin contact right?

You will not catch herpes by talking to someone. ref: https://www.cdc.gov/std/herpes/stdfact-herpes.htm (You may want to speak to a therapist regarding your health fears. Dwelling on these things can impact your quality of life)

You will not catch HSV by talking to someone even with lesions of HSV, You may wish to consult a doctor about your anxiety. In the meantime, start exercising. Begin with low intensity exercise such as walking and gradually increase the intensity so that you sweat profusely. It may take a few months for the full effect. Wish you good health!
