Social anxiety while pregnant

Im moving tomorrow to another side of town. It may sound stupid but im scared of running into people in public. I wasnt always this way.. ive become more scared since becoming victim to assault. Im 32 weeks and a few days pregnant.. my anxiety is worse than its ever been.. my boyfriend doesnt understand that theres some people that im actually terrified and im nervous about going to the store or anywhere in public because i constantly see people i know. Im scared of running into someone from my past and im scared they will try to talk to me or approach me. I feel more vunerable while pregnant. Is there anything i can do to feel safer?
