One tends to find out who was really a friend when a person faces their darkest moments and that as they look up their true friends are still there.
A true friend will always help you out of a situation rather then moan that they have heard it all before.
You can gather strength from them in your hour of need and they can see the courage that we all have to have to go on.
So if you have Strength and Courage on your side although sometimes it mightn't seem like it you have a lot .
I hope that helps
