I can tell that from your post that you want to do all that you can to be the best individual, wife and mom that you can be. So do not feel guilty, or that you have failed...like CM said, you are a hero and should feel proud for hanging in there!
Talk to your doctor honestly about your situation and feelings. Let him/her help you to come up with and anxiety management plan. Whether it be medication, or therapy...or a combination of both...you will find a way to proactively deal with the obstacles that are in the way of your feeling well.
There is hope. I found much relief through therapy, and am in a much better place than I was a few years ago. It takes time, but you can get recovery!
Keep posting with us. We are listening.:)
