3 months after stopping an antipsychotic (Zyprexa)

Hi,

I used to suffer from acute anxiety and panic attacks. I tried various anxiety medications, but none provided relief. My psychiatrist suggested trying an antipsychotic (Zyprexa), which finally gave me 100% relief from anxiety. I continued taking Zyprexa for 4 years, but it also caused emotional numbness. After 4 years, I couldn't tolerate the emotional numbness anymore, so I decided to stop the medication. With the help of my psychiatrist, I tapered off it slowly. It has been 3 months since I completely stopped the medication, but my anxiety hasn't returned, and the emotional numbness persists. It feels as if I'm still taking the medication. Does this mean that Zyprexa caused permanent changes to my brain? Can I ever overcome this emotional numbness? Could you please provide some insight into this situation? Your help would be greatly appreciated.
