Which SSRI is best and less side effect? I have social phobia. Ocd. Some time Stammerer. I take symbyax (fluoxetine and olanzapine) three or four day in a week.

All. No SSRI is better than other when it comes to side effects and efficacy(ability)
Seek Psyche help. It is better if you consult a psychologist or psychiatrist. he/she can help you with medication and offer you cognitive- behavioral therapy(CBT) which works better than medication alone.
