PP anxiety

Okay ladies. Around 4 months into being pregnant on quit work and practically stayed home for the past five months. Not going anywhere. No stores nothing. It gave me anxiety. My baby came a month early and is currently 2 weeks old and i have this extreme fear of going out places because I get anxiety, start to panic, and can't breathe. I freak out. No joke. I feel like I'm holding my life and my hubbies on hold because I developed this out of nowhere! Constantly focused on my breathing and I just want to know if anyone else has developed this or has ever had this and has answers on how I can get my life back. I've felt with this for almost Six months. I need help and advice please.
