Jo, Is there any reason why you can't carry MACE or Pepper Spray? If so, do it and never leave the house without it!! I carry mine on my car key ring. I've only had to use it once and that was on a dog that was trying to get to me while I was out walking.
As far as everyone staring at you.....just smile.:D You are so beautiful that just maybe they're looking at your face and not your disability.
Have you thought about volunteering at a local school to help kids read? Or possibly, a retirement center to help with elderly people? Maybe a card club. That would put you into contact with other adults.
