I am not going to speak to my mother for a few months
Why won't you speak to her?
I'm not going to talk to her because of the bigger issues going on right now
You are not showing respect for your mother and that is wrong. You need to keep in contact with your mother or she will not be available for you when you need her to be.
She is going to pay for it. I will make her feel bad.
I don't quite understand what it is that has come between you, but it is wrong to try to punish your mother so much over it.  Whatever the issue is, once you are feeling a bit less angry, you should bring it up with her and let her know how you feel.  If you shut her out, you will never be able to get a real solution.
