Thank you everyone for the supportive posts and advice. I am sorry at the delay in replying, partly because I was waiting for MN to move the thread, as wisely suggested, and partly because it has been a difficult few days. MN couldn't move the thread to 'Off the beaten track' because it is more than 30 days old, but they have taken it off 'trending' to try to keep it 'under the radar'.
Today is 7 months since DH died and tomorrow will be the first wedding anniversary without him. DD3 is coming home today to spend tomorrow with me and DD2 and we will have a low key day, probably have a takeaway and maybe watch a film together, nothing too demanding. This will be the most difficult 'first' for me, as birthdays and Christmas etc existed before I met DH, but the anniversary relates solely to him or, rather, to us.
Regarding the will, it was never my intention that DD2 or DD3 should be subject to the 'six month' clause, as trustees would be excluded. I think that I have been too fixated on death because of thinking of DH and how quickly he moved from never being ill (he had less than a week off work in 35 years) to dying. I saw DD3 earlier in the week and we were discussing spirituality and faith, which she thought might comfort me. And I said, yes I have been thinking about this and I want to have my funeral in a church according to the rites of the C of E. I have also been planning my funeral in my head. DD3 said that I had gone straight from a general discussion to talk of my funeral - and of course she was right. I need to put my affairs in order, so that I can then forget about it and try to live.
I think it was Justilou who asked whether I had real life friends to support me and the answer is yes, I am truly blessed with the number of people who care for me. My oldest friendships go back for half a century, and I have been lucky enough to find others on the journey to this point in my life. Now that lockdown is ending, I have had a lot of invitations from people, from going out for lunch or taking in an exhibition etc, to going to stay with them. And I am easing my way back in, but when I do see my friends, I know that they will be sympathetic - that's a given - but I don't want them to be my therapists. I want to look for the joy, to try to find some light after the past 18 months of darkness.
I have four friends who are widows and they are the ones I talk to about DH, because they understand. The loneliness and isolation come from the void left by DH, and that cannot be filled. It will always be there and I just have to learn to live with it, like an amputee who has to learn to adapt to a prosthesis.
Anyway, regarding the will, I will have a discretionary will trust, with strict conditions, so that it is to be used for things like education training, enrichment, or if a beneficiary is in need. Also, housing, although I hope to be able to help DD2 and DD3 to buy their own homes when they are ready. Each family ie each of the DDs and their DC, if any, should inherit a third, but it will be at the discretion of the trustees as to what the money is spent on. However, so far as I am aware, I am in good health and may live for another 30 years, so the situation could easily change before then.
I also think that I have become a bit paranoid about DD1 and, to be fair, I think she is a bit paranoid too. I guess that the trust between us has been significantly eroded and it will take some time to be fully restored, if it ever is. We had one of our telepathic moments on Wednesday evening, when I sent her a message to ask if she was ok, just as she was about to ring me. It seems that they had spent the previous few days frantically searching for properties and have offered the asking price on one in County Mayo, which had just come on the market [link removed at OP's request]
The price is low, at just under 100k euros, but it is not habitable. It seems that LB might go to Ireland for 3 months to make it habitable before they follow him. However, the neighbour had also made an offer and I haven't heard anything further from DD1, so I suspect that they haven't bought it or are still negotiating. They can't visit the property because of Covid and they are anti-vaxxer anyway, so I am not sure when they would be able to visit.
DD1 was waxing lyrical in our telephone discussion, about how it had always been their dream to have a smallholding, not to farm, but just to be self -sufficient. They are looking for a long term project. She has been researching how to buy and butcher pigs, as there is a lot of meat on them. She said you can buy 'weaners' for 50 euros, fatten them up, and then sell the meat for 200 euros. And this is a former devout vegan!
On the positive side, she said I was welcome to visit anytime, as they have no immediate plans to go anywhere, and she will take me to her local butchers, which is excellent!
Gerwurtztraminer (I love your user name!) - you have my sympathies. Your niece's DH sounds just like LB, he doesn't like people disagreeing with him either, especially women!
lego - thank you so much for the sympathy and hugs and indeed thank you to all of you for the ongoing support.
Dithercats - you are totally right, nobody's love can be bought, and I am sorry to hear about your situation.
gonow - thank you for the recommendation of H G Tudor. I haven't heard of him but I will look him up. I also have some recommendations from the incredible Ssloou, whom I had the pleasure to meet last week and who is just as wise and lovely in person as she is on this thread.
Random - you make some valid points about how LB could target monies given to DGC, but I suppose that there is a limit to what I can do.
The other thought which has been bubbling in my head, but I am not sure where I will go with it, is to set up a charity to help those with oesophageal cancer, especially in trying to make people aware of the symptoms much earlier, when there is more chance of a successful outcome. Unfortunately, most people are not diagnosed until stage 3 or 4, by which time it is usually too late and survival rates are very low. A close friend lost her mother and sister to ovarian cancer and set up a charity, which is now one of the leading charities for the detection and prevention of ovarian cancer, and has saved lots of lives. I would like to do something similar and I am sure that she would advise me how to go about it but, at present, the grief is still too raw and I don't have the energy. However, I am full of admiration for what she has achieved and would like to do something similar.
Triffidealer - You might be right about ASD, as DD3 has recently been diagnosed and her therapist told me that it is usually genetic and runs in families. With hindsight, DH's father and aunt definitely had some of the characteristics, but we just put it down to individuality and eccentricity. Thank you for you kind wishes and also to zebra.
