Hi Lynnmarie and welcome to SR. Congratulations on 3 months! That's huge.
I still struggle with anger. It was a bigger issue when I first quit. It is normal and it will get better. I try to take time outs for myself. Counting to ten before responding works. As does the serenity prayer. Even if you aren't religious, it is helpful to understand that we have no control over other people or things, only ourselves and our reactions. We do have a choice.
Hope to see you around.
