the best way to get over something is to accept the pain. acknowledge its there, and completely understand where its from. embrace it. understand that nothing will ever be the same again. don't get hung up on it, because getting hung up means staying with the issue.
then, over time, you will start thinking about it less, and less, and less
and suddenly....
it'll just be a past memory, only brought upon on certain occasions and regarded with faint feelings
