I would say talk to your doctor and see what they say. I know that once you get it you are more prone to get it again. As for BFing you have to do what is best for both of you. I didn't BF my first and felt so guilty about it. It has taken me years to realize she is just fine even though we couldn't figure it out. Please don't feel guilty about it. Formula is not really the evil thing and kids do just fine on it. If you need someone to talk to I would call you physiologist or find a girlfriend to listen. ANyone who will help you work through your anxiety. Anxiety is the worst IMO. I hate the way it makes me feel.

I hope you can start feeling better soon.
