I hope you're getting correctly treated for the UTI. Drink lots of fluids including cranberry juice if you can. If you can afford it, take a one-time pill for the yeast infection, a single dose antiviral for the herpes, and have you been eating chocolate by any chance? Chocolate contains arganine, an amino acid which feeds the herpesvirus. It can be partially counteracted by taking lysine supplements, and in fact anyone with herpes should probably take daily supplements since arganine is found in a lot of foods. But chocolate is one of the worst, and even megadoses of lysine can't fully counteract it.

I'm sorry. You must really be feeling as if your body hates you right now. Please remember that this will eventually pass and the teeter-totter of life will eventually go back up again.
