It comes out very good for you to do seven nyung-näs.
You should also write the Arya Sanghata Sutra three times. This is to collect extensive merits and purification to reach enlightenment quickly. The aim is to liberate sentient beings as quickly as possible from suffering and enlighten them.
If you can, request the Gyuto monks in Dharamsala to read the whole Kangyur for you.
Both recitation of the Kangyur and writing the Sanghata Sutra can also be dedicated to the long life and success of all the holy wishes of His Holiness the Dalai Lama and for the quick success of all the other projects, like building holy objects, especially to be able to build the Maitreya statue. It can also be dedicated to being able to serve all the monasteries, big or small, and all the Sangha, so they can spread Dharma in the world.
Whatever puja you do, first, of course, you dedicate it to yourself, but secondly it can be dedicated to all these things.
With regards to having the entire Kangyur read, first check the costs and see whether you can manage it. Otherwise, you may need to rob a bank in Europe, which might be difficult, because there are always too many people around. Or your long shamtab might get caught, or even your Chogu (in case you want to rob the bank dressed up in your robes and Chogu).
Also, it is very good if you can make 35 long-life tsa-tsas (three long-life deities in one mold).
If you can, recite Most Secret Hayagriva mantra, and after each mala, blow on a container of water—blow on the water, not the container, unless you can do magic and make the container itself turn into water (like the nun from Dharamsala). Then, drink the water five times a day. This can also be to quench your thirst. Take a good mouthful of the blessed water, not just tiny sips like a mosquito! Do that for a few months.
Also, take one small teaspoon of Dorja Phurba powder twice a day, for two weeks. You can get this from His Holiness the Dalai Lama’s private office, they often give it out (like mani pills), so you can ask someone in Dharamsala to get it for you.
My dear Nina, please do not have the operation now, do this first, and then we can check again.
With much love and prayers...
