i have Agoraphobia too i cant go out the house with out my husband with me
because i think am going to hit people and i have voices that tell me to do this
I cant go on buses on my own and i find that am really panicky on them if am not sitting on a set seat
Am loud when i have a panic attack it can upset other people and it takes a long time for my husband to calm me down

It does sound like Agoraphobia to me
