Can relate, chemical stuff plays a role on it, when i say chemical stuff i mean the central nervous system reactions, i couldn't peak up the phone at all, couldn't answer the door, Felt overwhelmed with brain stuff(elecrtricity-like) while talking on the phone, and agoraphobia plus there is aswell the whole particular stuff that hits you psychologically , i dont link this with the agoraphobic responses, Im Still kind of agoraphobic, not fully but Just dont feel well enough... Cant wait for such a thing tô fade like others symptoms , hold on It Will get better
