Got diagnosed with OCD and prescribed Prozac. Please, read this.

As the title says, I recently got officialy diagnosed with ocd ( Schiz Theme ) and got prescribed Prozac 20mg per day. I've been taking it for a total of 9 days and I think I started to feel even worse. I had a total of 3 panic attacks for those 9 days and I was having panic attacks only for the first 40 days of this theme (6.5 months into it). This really bothers me, because i somehow managed to get rid of the panic attacks on my own and haven't been having any for 5 months straight. My sleep got really disturbed, nonstop racing thoughts and nonsense thoughts and even made up words popping in my head when falling asleep or waking up. This was something that was gone too before the medication. I also lost my appetite completely, having only 2 meals for the last 2 days and I am feeling nauseous. My anxiety has increased at least 2 times. The only thing that seems better , and i mean a little better , like 20-30% are the intrusive thoughts. But i think I am so overwhelmed with anxiety and panic and fatigue, that I can't even think about the intrusive thoughts the way i normally do. Is this a normal reaction for the first days of SSRI treatment ? I am really concerned. I used to have some good days before I started it.
