This is very similar to me. I understand. I've been anxious for a long time but in recent years, I've started to experience my anxiety mutate into paranoia. It prevented me from going to school, seeing friends, maintaining friendships and ultimately kept me locked up in my house where I feel safest but preventing me from experiencing and seeing so much. Irrational anxiety really, really is horrible I'm sorry to hear you're experiencing this I hope it lifts and becomes a thing of the past real soon
