Hiya,
Sorry for taking so long to post to this message.
I have those feelings, I am petrified of being alone in the house.
I have to check daily if any of my neighbours are going to be in that day, I'm always looking out the window to check no one is going out of the building. Even if I know someone is in the building I still feel panic starting and have to jump up and down and say to myself. THERE IS SOMEONE IN, I've even found my self phoning my neighbour and putting the phone down when she answers, just to make myself feel better knowing she is in.
Best wishes Donna aka Venga
