Hello my name is Gloria and I have been suffering from panic attacks and depression on and off for 23 years. I was doing well for so long that I thought I was passed it all. My life is good. I don't have anything to be worried about yet here I am again at the age 44 having panic attacks again. I have started on 20 mg. of prozac again. Also l am using Xanax when the panic attacks get really bad. Mine escalate to thoughts that I'm losing control and going crazy. I also fear that my medication won't work this time which has never happened. I've always done well on Prozac but this time around I feel like maybe it's not helping. I just upped the dose to 20mg about a week ago. I haven't even been on it for a month. I know it need more time but I just can't shake this feeling that it's not going to work this time. I guess I just feel hopeless and I thought I was passed all this. I'm hoping someone has had these feelings and can reassure me that my meds will work. And that again this well soon pass as it has before.
