There's no particular way to overcome it. It changes you in a way. For me, I moved away from the city. And never looked back. But from time to time, I still break down and cry, after 2 years. I think we don't overcome, we just have to live with it. I really don't know a way of overcoming it. My regards to your cousins and uncle. Tell them to be strong and go on living their life because that's what she would have wanted for them.

Take care and huge hugs @florecitamejias
