I've been on fluoxetine 20mg for about 11 days now. I have panic disorder and I constantly feel like I'm always about to have another panic attack any second and I've been like this for about 4 months now. I'm not feeling any kind of a difference ever since starting the medicine, even though I keep telling myself that it takes a while for it to help. I'm super impatient partly because I don't wanna feel like this anymore, when will I get better??? Thanks.
