Anxiety is Back :(

Before I got pregnant I had terrible anxiety attacks or what I considered terrible. I wasn't worried about anything other then TTC and starting a family but I felt like I always had a heavy heart. Well over the last couple days it has been coming back. The high of pregnancy and BFing is wearing off. What am I going to do? I have throughly enjoyed this break and feeling sane for the first time in years. It might be time to talk to my PCP. I am just not ready to give up BF and I think the only way to get rid of this is to go on HRT which means no BFing :(
