Look into narcissistic personality disorder if you suggest you think she has been doing this all her life. I have a mother just like this.. also cognitive dissonance is extremely strong it sounds like. Anyhow.. I grew up in this kind of stuff I actually left family for 10 years and I suddenly got better after about a year or 2 of no contact. I recently got back in contact because she has cancer. She is exactly like you are describing.. I can see it very clearly after years of healing. I say this based on what you describe you are almost describing my experience to a t and in fact some conversations that happen this evening.
If it is a recent thing then might be something else.. but you said you think its been happening your whole life.
