People who have had very difficult and bad childhood will unfortunately be forced to deal with these fears in their life as adults. If you have compassion for them then you should try to help them to get through these things because it can be very difficult especially if someone is alone. If we can all help each other in this way it will help the next geenration of children, because, people with problems like that can pass them on through their actions so if we stop that and help them become happier then it will benefit everyone.
