LET GO
Letting people go is a very hard and painful process. It is even more painful if we are stuck in a childlike emotional state, because for a child, losing their parents meant death. So we fear it the same way we fear dying.
But life is dynamic. Everything changes. People change, and we change too. Our goals change as well. Sometimes it is better to let some people go for the mutual benefit of everyone involved.
At first, we may feel devastated, just as children would if their parents left them. But we are not children anymore, and eventually things return to a good state. Yes, we may feel very bad for a while, and that is a normal part of life.
Whatever needs to be felt needs to be felt. Avoiding these emotions only makes everything worse.
It's the time to move forward.
