I just started taking Lexapro about 4 days ago, so far I have not really noticed a change.I am 23yrs old & I suffer from OCD negative/irrational thoughts on a day to day basis. I am always afraid I will get into a car accident, or crash my car, or harm myself/others.(always about death and afraid of it) I have been in counsling for about 6months now, and my PCP prescribed me this medicine. I was just wondering if there are other people out there that have thoughts like this, and is Lexapro a good medicine to help with OCD/Aniexty. If so, when did anyone start noticing results. Just knowing I am not alone, is such a HUGGEEE help!
