Panic attacks following Depo-Provera birth control shot

I started Depo-provera on the 1st of May. I have had a little bit of axiety but nothing unmanageable. 2 weeks ago just before I was due for my repeat shot I had a small panic attack, I didn't know what it was at the time and just took some stressaway and meds for my stomach. On the day I went for follow up shot I had 1 medium panick attack leading into a major one within 2h of having my shot. The doctor thinks I have panic disorder, is it possible that this is all because of the depo-provera?. Please help!!!
