One of the things that people say about anger is to "Let it go."
You have to let the anger go and forgive. Its good advice, but most people don't actually MEAN "let it go". Most people mean, "Repress it, shove it away and don't talk about it."
"Let it go" means I won't be able to control it. "Let it go" means that I let whatever is going to happen, happen. "Let it go" means I stop hanging on to it and actually "let it go".
If I am holding on to a wild tiger. I don't want to let go, because it might hurt me. I'm scared to death. However, once I let it go, it leaves. The tiger doesn't want to hang around - it wants to go home. I could put it in a cage, but then I have to take care that it stays in its cage... If I let it go, I take the chance that it might hurt me...
That's what anger is like. I could put it in a cage, but then I have to work hard to keep it in its cage. It doesn't like its cage. It wants to be free. It doesn't even want to hang around me... So, I let it go.
It lashes out for a moment, until it realizes its free, and it goes away.
So, don't tell me to let it go, unless you actually mean let it go.
And, don't tell me to repress it, because I won't listen anyway...
