I'm sorry for the breakup with your mom, and for your other troubles. We do indeed have cycles of trouble and bliss, and I hope you get through this cycle as quickly as possible.
Keeping some distance from your mom sounds like a good idea. The old saying, "Absence makes the heart grow fonder" exists for a reason. It doesn't always work that way, but in family it will probably hold true eventually. You both may need some time and space to heal from the hurt.
Good luck as you negotiate your way forward! I'm sure you'll find a good way.
