My advice is to see your doctor as soon as possible. I would definately recommend against stopping your meds for a few days as the levels that you have built up in your system will fall and you will probably feel pretty bad when you go back on them. See your doctor and see what he/she says. It may be a case of changing your dosage or the med itself.
I am sorry this is happening to you. A side effect of Prozac is loss of emotional feelings. I too recommend that you see your physician ASAP and please do not harm your self. If you feel like you are going to do something hurtful please call someone immediately, or present to the ER.
There are many other meds to choose from and of course you want to have feelings not block out all your feelings but I agree to talk with your Physician before discontinuing the medication.
Gentle Hugs to you.
