I feel embarrassed to be alive
I'm posting a question for the first time.
My grandmother passed away 4 years ago, and as a grandmother, I was very sad at the time. But at the same time, around that time, I began to feel ashamed that I was alive.
In the few years since my grandmother passed away, not only the person herself but her family had a hard time with nursing care. There is a section where I also felt irritated and disgusted by my grandmother, who had been raised so well. After that, my grandmother passed away, and I deeply regretted what I had done up until now. My grandmother raised me at the cost of her own pleasure, but at the end of the day she suffered and died, and I never stopped wondering how bad I treated her, and that I couldn't have been more kind to her. After a few years, I became a member of society, but my job wasn't very good, and I even think I can't face my ancestors who raised me up to this point. I feel sorry for being alive when I think of only receiving favors.
What is the correct answer for me to feel like this from now on? Furthermore, I'm afraid every day that what I've done will happen to me in the future. Could you please lend me your wisdom?
