I' pretty sure I have ocd and have been on fluoxetine for the last couple of months. My obsessions which had to do with repugnant thoughts got really bad and caused me to have high anxiety. After a few weeks the prozac really seemed to be working although the ocd was still there but nowhere near as much. Last week though I seemed to have another attack and can't control my thoughts again. My hands wont stop shaking and it's almost impossible to study. My isn't the fluoxetine working anymore? It was good to feel normal again even if it was only for a few weeks. How do I stop myself from getting so stressed?
