Anxietygirl,

Next time you see your doctor just let him know what you've told us, that you can't function without it. Give him a couple of options such as trying another med or upping the Lexapro or going back on the Klonopin. I would also suggest you get into therapy if you're not already. Know that you also have to find a therapist that fits. I'm highly biased towards pychoanalytic therapy because it is what helped me deal with my past trauma's and overcome complex PTSD and OCD as well as Anorexia and Bulimia. But your treatment is your choice, just try to do something apart from medication otherwise you'll always be dependant upon the meds.

Love and Hugs,
Tara
