How to do deal with toxic family members?

I have a toxic parent who complains , complains, and complains about any and everything she has nothing positive to say about anything. This is from the time she wakes up and goes to bed she finds something to grouch about. I actually called my mother a grouch because she is extremely toxic and negative. I ignore her and the rest of the family who lives with her. The only time we have peace of mind when she is quiet - she creates drama to hear her self talk.
