Have you ever avoided doing something that you know you should do? I'm not talking about general procrastination, but those things that are a bit scary but that you know will help you move forward, learn, develop, whatever.
As Anais Nin said:
...and the day came when the risk to remain tight in a bud was more painful than the risk it took to blossom...Sometimes resisting the thing we know we should do causes more damage than facing the pain or fear of just doing it. It stops us from moving forward; from blossoming.
This is often the case when we need to forgive someone. The more we hold on to the hurt, the more hurt we become. I like to think about it as holding on to barbed wire: if we would just let it go, the pain would stop and the wound would heal.
Where do you need to blossom?
