I'm going to cut off my parents
Have they done you wrong?
Yes.
You can't choose your family, unfortunately. It may be awkward or painful, but removing toxic people from your life is only a good thing.
I really wish they wouldn't behave the way they do, but they are toxic. Cutting them out might be for the best.
I agree with you there and support your decision. I hope they come around in the future but for now all I can do is wish you the best.
