That is probably the most disheartening thing I can imagine happening. You must be feeling just desolate!
It is painful for everyone when families fall out, and however mad your daughter is, trust me that she is also suffering a lot of turmoil.
You are in the unenviable position of being completely powerless in this situation. If your daughter simply will not accept your apologies, promises to never tell her what to do again, vow of a non-critical future, or anything else, there is absolutely nothing you can do about that. Or, rather, there is absolutely nothing that you can do about it that won't make the situation a whole lot worse.
No matter what your intent was over the past 32 years, your daughter has perceived your response to her as judgement, critical, a lack of love, or attempts to control who she is or how she lives her life. Whichever one of those you think is most likely is probably accurate -- it is my experience of mothers that they know their children very well, indeed, even when relationships are rocky. Whichever it is, the solution is the same: unconditional love.
From here, with or without her ever accepting your love in her life ever again, the only thing you can do is find the unconditional love for her within yourself. Beating yourself (or her) for the past misunderstandings or ineffective approaches is a waste of time, and a cruel thing to do to very nice people. If you spend your time between now and the end of time feeling victimized by her choices, finding fault with her or explaining away why what you did was 'fine' you'll find that if she contacts you again it will be very difficult to avoid spewing that onto her out of the tension that trying to force an immediate 'fix' to everything will create.
On the other hand, thinking of her in unconditionally loving ways will give you a foundation of goodwill toward her that she will experience immediately if she ever decides to let you back into her life. Unconditional love will give you a sense of tenderness and patience that will be much more helpful if she ever braves connecting again.
If you find it helpful, creating a practice of meditation or prayer that is specific to healing this relationship will give you practice thinking of her in a gentle way, which will greatly improve your life in the meantime whatever happens, and protect you against reverting to the last angry thought if she contacts you at a stressful moment.
You are grieving, with good reason. One of the things that is no doubt being a tremendous frustration is knowing that the outcome is, truly, out of your hands. Open your heart to the pain of your loss and you will find, in time, that you can accept the choices your daughter has made and remain accepting of yourself, too. No one is the bad guy, here.
