Your doctor is there to help you, and if what is being done isn't helping, you just come out and say so. There is nothing to be afraid of. Just tell him how you've been doing on these meds and your concerns. Don't be scared to tell your doctor anything. He's there to help you, and if you don't tell him what isn't helping, he can't do that for you.

Hope you feel better soon and can figure out, with your doctor's help, a better treatment plan.
