Write it all down, all the feelings and all the nasty words, all the hate, get it out. Then burn the paper with all your emotions on it, and give them back to the universe. The universe is such a huge place, that it can handle all your negative stuff.
Google "The Red String Book'. Simply read it, its short, and to the point. It is not a religion but a science.
Many years ago, I had had enough of my interfering mother, and all her blasted 'suggestions' about how I should run my life. I got to and made a scarecrow, went out a put her on the fire, as she was burning up, I told her exactly what I thought of her and I felt, by this time I was drunk, and having a pretty good time of it, I really gave it to her 'the mother-crow'. and you what? ever since that time, my mother and I have had a much better relationship. I do this a lot. However now I do write a lot of it down and simply burn it.
Bless you and good luck
