This is Kawaguchi Hidetoshi. This is a humble answer to the question.
I was also allowed to deal with “My Parents, Thank You,” even in the following question.
Question “My parents are too disloyal and painful”

Question “I'm taking care of my parents in a situation where I have no choice but to separate from my husband”

Of course, the “Parental Gratitude Sutra” is a sutra established in China, and the influence of Confucianism is strong, and the false sutra theory is dominant, but I know that the content is important when thinking about parents' kindness.
Probably, UK46's mother will always be worried because her “daughter” will always be her own child, and in particular, UK46 is also undergoing medical treatment for her illness.
I also think the mother would like to listen to her voice and confirm that she is doing well. While being told that it's okay, don't worry, I'm doing well, it's still a little tough every day, and if you want them to reduce the frequency a little more, for example, every phone call also charges a phone bill (it doesn't matter if family calls are free...), so if your mother has a cell phone or computer, you can exchange messages and emails, or if you have a fax, maybe it's okay to exchange faxes I know. I also think that would be more comfortable and flexible with each other in terms of time and convenience than a phone call. Of course, it may still be difficult if your mother is elderly and not good at machines such as cell phones or computers...
However, I also know that you can take this opportunity to feel the kindness you have received from your mother up until now, even from your parent's ten blessings in the “Parent's Thanks”, and I also hope that you can feel even a little relaxed and have room to accept them. By all means, I would be happy if you read the details of the Ten Graces of Parents on the following page.
