It isn't easy and there are struggles, but it will be good again.
I think this is really important to understand. Life isn't orderly or fair. Bad things happen to good people. Sometimes randomly and sometimes as a result of choices we make.

If I could go back and change some of my choices, maybe I would be a successful author with living children, making loads of dosh and paying most of it in child support to some douche of a sperm donor. Or maybe I would have been killed in a car accident or become a drug addict or drowned or been raped and murdered or won the lottery or travelled around the world. The thing is, we'll never know about what happened in the parallel universes where we made different choices. All we can do is deal with the what we've said and done as best we can now.
