You are definitely not alone. Estrangement is rampant in our society today. I have managed to find a support group online that has helped me see it for what it really is. Many of our stories on that site ( and so many other sites ) are similar, we are all victims of the "me first" generation. Only our shortcomings stand out to them, no respect or appreciation for all we did for them raising them. Even the ones who have the same challenges raising their children we had. Somehow they imagine that they are wonderful parents. I realize there are some reasons physical or sexual abuse that do require cutting parents off. Usually their reasons for detaching (if they even divulge their reasons ) are much less serious. If we dare to disagree or offer advice without being asked - you are deemed "toxic" and of course all the meme's on their bible - Facebook tell them that they should exclude toxic people from their lives. Even family. The unconditional love is only a one way street, we the parents are expected to have it for them but there is no such reciprocation from them to us. Once they have the ideal blackmail weapon ( grandkids ) they are not afraid to use them to teach us a lesson....er whatever that is supposed to be, other than they are of horrible character. It matters not that they are denying their children bonding and love and support from good grandparents. If they let you see them now and again then they feel their conscience is clear. No bonding tho. That might mean they would have to be cordial to us shunned ones. Unfortunately they are showing their children how to treat their parents, and their reward will be the same shunning. Of course they don't believe that as they view themselves as the "enlightened" generation. And of course even if they ever realize that the punishment they dole out to us doesn't fit the crime , there is NO chance of an apology. If they can't find a good reason for cutting you off, well they'll just make one up or exaggerate some partial truths. If you acquire an illness or neediness of some sort, get over it, so that you can concentrate only on what they need from you. Your age or your health is of no concern of theirs, in fact you probably didn't look after yourself properly so that you could be acceptable to join them out in public. If you aren't 100%, don't expect them to close ranks to assist you, rather expect to be excommunicated. They are unwavering and have no guilt. And if you have other children or they like the other parent, expect them to try to enlist them in the shunning. Sorry to be so blunt, but I belong to a couple of groups of as you put it rejected parents and this sums up the way it usually goes. There is of course a journey to acceptance of the reality. It is found that grovelling, apologizing for whatever it is that makes you less than, reaching out, even begging only fuels their fire. Eventually the ones who have been in the situation long enough decide that they've suffered enough for what they don't deserve and close the door. Again, sad for the grandchildren. But their children's happiness is way way behind their need for revenge against perceived sins by their parent (s). The main thing to remember : It's them, not us who are less than.
