I just spoke with a good friend who was having a few problems and think I helped him. His mother died and he was also having a insignificant argument with his son.
I told him, you will always work Through the one problem and the the other you need to get Over . Some things in life you need to get Through and others you need to get Over.
Through = You constantly work through a death or a loss making it a memorial for you and loss on a daily , weekly, monthly or yearly event. This can be a resourceable energy.
Over = A non significant event that is not worth the time or effort in your life that can drain positive energy.
