Refuse to take antibiotics for infection

I went to the doctor yesterday and found out I have a urinary tract infection. I also had some blood in my urine (couldn't actually see it) and was slightly dehydrated. They prescribed me antibiotics but I don't want to take them. I read what could happen and it said that it could lead into a kidney infection and that could lead to like an infection in my blood and eventually shut down my organs. I told my therapist yesterday that I wasn't going to take medication for it and I wanted it to kill me. (I have a long history of SI). My husband is also aware of this and told me he would make me take meds.
Can they make me treat it?

D-mannose is a sugar with a 5 carbon ring. It is one available in drug stores and on Amazon.com. It is not the only one. These 5 carbon simple sugars cause bacteria to stop clinging to the body so that they can be flushed out. They can be used - suggesting this as an alternative for you to properly investigate for yourself - as an alternative to antibiotics for a UTI. It is better than cranberry juice.

Kidney failure is a bad way to die. From a UTI, I think it would take several painful months to simply allow it to happen. My guess, though, unless the infection is especially severe or your immune system particularly depleted, is that you will simply have to urinate all the time and you will become dehydrated. This will lower your blood pressure until you faint somewhere in public and wake up in hospital with an IV of fluids and antibiotics.
