What I make of this crazy, contradictory person is that she's been as deeply damaged by her upbringing and life experiences as you probably have been. The strategies she's employing in an attempt to meet her very deep emotional needs are very poor strategies, and she can't see how disturbing they are to you. She simply can't, and unless she gets serious counseling to help untie the emotional knots that she's tied up in, she most likely won't ever change. She simply won't be able to.
I suspect you are tied up in many of the same knots. You are trying some of the same strategies your mom is employing – trying to (or at least desperately wishing to) change the other person to meet your own needs. Sweetheart, it won't work. You cannot change other people; it's hard enough to change yourself.
Get the professional help you need, or you will unknowingly continue feeding the cycle of dysfunction, and quite possibly pass on your own problems to your daughter. YOU have the opportunity to break this awful cycle. Get help; good counselors are available everywhere. If cost is an issue, check with your county's mental health services, which may be available on a sliding scale.
My mom is quite a lot like yours, in her need to wring admiration and affection from her 4 daughters, in her absolute need to control us as if we are puppets she can bend to her will. I was well into my 30's before I realized she will never be anyone else than this toxic mother to me. She is hell-bound by her beliefs, which are rooted in the unfortunate circumstances of her own birth and upbringing.
But I got some help, and I will tell you, it made all the difference. I was finally able to stop trying to be the "obedient little girl" my mother demands, and find healthier means of meeting my own emotional needs.
This is ongoing work, some 30 years later, partly because we live next door, partly because my mom is becoming pretty senile and there is still some small part of me that hopes she will someday recognize and love me for who I am. But that's not realistic. So I am doing my own healing, which at this stage means carefully limiting the amount of contact we have. When I do this successfully, I experience less distress. This disappoints my mother, of course, but over the past 30 years she has slowly learned to accept my distance.
Stand back and look at your situation, A.. You may be able to see that your mom's need to control you has created in you a need to control her, to make her different/better/more loving. It doesn't work when your mom expects more from you than you can give, and it doesn't work when you expect more from your mother than she can give. Find a counselor who can help you let it go, so you can find your most authentic self.
I wish you every success.
