My wife and I have a lot of problems with our 30-year-old son. I am 62 years old and my wife is 56 years old. We have only one child, our son has a problem with depression and pessimism of ancestry to others from 10 years ago. Because of his high tensions for us and sometimes physical conflict, we had to oblige him to separate from us and live elsewhere. Many times we tried to connect him to a psychologist, but he refused every time.
Because of huge stress , unfortunately My wife was diagnosed with thyroid cancer and after one year she has been diagnosed with MS since four years ago.
Still, our son puts severe mental pressure on my sick wife and me with his daily calls. He is pessimistic towards everyone and uses rude and hateful words.
Unfortunately, he does not accept any way to treat himself and only believes that he will relax by smoking marijuana.
Please guide me, considering that my wife is sick, how can we be freed? Or how can we treat our son?
