Hi Gypsygirl,
It's okay, you can get through this. Finding the right medication or combination of medications can be very frustrating and time consuming. If you hang in there you and your Physician will find one that works best for you.
Do you have a Benzodiazepine (Valium, Xanax, Klonopin, ect) that you can take to help get you through this difficult time.
Is there a reason you were only on 5mg of Lexapro and not increasing to a higher dose? Lexapro at 5mg isn't going to be very helpful
