I'm so sorry this happened to you. It must be really frustrating. The free samples sounds like a great idea, but if your doctors office doesn't have any free samples, see if they will write a prescription for only 4-5 days worth of Lexapro for you that you could have filled at a local pharmacy. That could hold you until your prescription arrives in the mail.
I hope everything gets straightened out very soon and you get feeling better.
