I am so sorry to hear about what you are going through. I found something today that helped to give me a sense of peace and I wanted to share it with you. It is about the art of letting go.
So the second thing we have to let go of is all of our judgements and values and ideas of what should be or what shouldn’t be. We should have no values, no judgements, no morals, no criticisms, no ideas of what is or should or shouldn’t be. None at all. Because if we have an idea of what is or what should or shouldn’t be we are making a judgement on something that is as it is, as God or as the Universe intended. It is as it is, and it is perfect as it is for the people who are involved in that scenario. That applies to us in our lives, but because it is a principle it applies equally to the people in a war crisis, for instance. And that’s where the understanding becomes really difficult to accept. You may say, “Hold on, this is not right” but it is, it’s right for them, and I’ll go back to a previous point. The angrier everybody gets about a situation, the worse it gets. This is not at all pleasant or emotionally intelligent but judging won’t improve it either; it will make it worse.
[. . .] Something that gives a depth of understanding is to recognize that the action is not the person. You can say that action is not good, but the person is perfect, they are perfect in as far as they have got in their own learning about life. We cannot possibly see what the master plan for the Universe is, so if we start judging and criticizing we are saying we know better than God, the universe, energy or whatever, and we don’t. We have to let go of the assumption that we know. Letting go
Basically it is about letting go of the pain, remembering that we all we have is right now and cannot control anyone else's choices. It gives perspective on how to handle the negative stuff.
