Ton of people have no kids or their kids live so far that they won’t be able to help much. I’d not count on that.

Other than that I am sorry she resents you. She is at the age when they think they know better. They don’t. They grow out of it and see things clearer later on.

You have legitimate illness yet you are working, paying taxes, not trying to cheat the system, not living off others, always bettering yourself, seeking mental health treatments and help, maintaining relationships with your daughter and other family as much as possible and in general contribute to society in whatever ways you could.

Even if you complain (we all do) you don’t mop around 24/7. It’s more than what other people do. Be kind to yourself. You are doing well

And who really knows about purpose of life.
