Hello,
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.
