My heart hurts

It hurts my heart to talk to my childhood friend on the phone.
I used to live next door to a fence, but my friend said that his health was very bad.
What makes it even more upsetting and heartbreaking is the fact that my son's late-acquired disease shows up in his son, and the moment he hears the word, his heart sinks, wondering what is going on.

When he said he was sick, yes, he said he was old, so he could take good care of him and receive treatment, but in the story of his son, that is not the case. It is heartbreaking to hear that a young friend with a bright future is at a crossroads between life and death due to an inherited rare disease of unknown cause.

The exact cause is unknown, there is no treatment method, and the suffering of those who lose this disease is indescribable. It's not a disease that is caused by your own fault, and what's more, if it's hereditary, what could be worse than this?

Regardless of the reason, I hope the government or medical insurance will completely solve the treatment cost. Otherwise, as an individual, I cannot bear it because I have to suffer double or triple.

I have suffered from a tumor on the skin and muscles of an unknown cause, but it grows inside the muscle rather than externally, and presses on the spinal nerve, causing unbearable pain. I can't and it's frustrating.

I was told that the artificial joint surgery was wrong and I had a reoperation, moved to another hospital on the 29th of this month, and had an appointment for a pancreatic biopsy on February 15, and after seeing the results, I need to make a plan for tumor treatment. It is said that the son's tumor surgery was decided on the 27th.

However, the problem is that it is very pessimistic, and it is even more sad to say that it is an operation with only a glimmer of hope. I don't really worry about things in the world, but I didn't know that my friends would break my heart like this. If it were just for friends, I wouldn't feel sorry for it to the point where it hurts my heart like this, but I'm really, really sorry.
I don't know what to do in this case.

I want to run and comfort him, but I can't visit him because of Corona, and even if I can't, I wonder what will change if I see his face once, and I even resent why the world is like this.

Is a world without accidents and diseases impossible? If there is a God, I would like to create such a world.
