Hi Shimmering,
I must echo what others have said. You can't control other people or the world around you. The only outcome you have any control over is your own. Bad things happen, and there's nothing we can do about that. But we can control how we respond to them.
On the issue of a higher power, to me you either believe or you don't. I personally could never get into that because I am not a religious person and I don't believe I can force myself to believe something that I don't. But religion and spirituality are not synonymous. I still believe that there is a force greater than what meets the eye. You can call it the universe, karma, whatever you want. But I believe it's there, whatever it is.
All you can do is work to stay sober and be the best person that you can be while you're doing it. Sometimes you simply have to trust that things will work out, no matter how impossible it seems. You just have to stay faithful.
Best of luck to you!
