Should you feel bad if you are not living up to your parents or society's expectations? In short, I would say no. This might sound a bit harsh and unorthodox, but basically I think we don't really owe the world anything, not even to our parents. The idea that we should always respect our elders is social propaganda from the Bible and other ancient writings or customs. In fact it was probably made up by some parents to mentally enslave their children through shame and guilt.
If we're being honest, it's the other way around, our parents owe us. Life is not always a gift, some people have to endure a lot of suffering. But there is no proof that we asked to be born. That choice was made for us by our parents without our consent. They chose to procreate and bring us into this world, usually for selfish reasons. No parent is doing their child a favour by bringing them into existence. So they are actually morally responsible for our well being, although nobody can of course force them to take care of their children either. But we are by no means obliged to serve our parents, or even to respect them.
That's not to say we can't help our parents. Personally I don't hate my parents for bringing me into this world, although I am not happy about it either. The reason is that I don't believe in free will. My parents were acting based on their biological instincts and cultural influences. They didn't know about the concept of antinatalism. Procreating was just part of the cultural zeitgeist and norms during the time when they made me. Also my parents have been generally agreeable, they haven't treated me badly and my father has supported me when I needed his help. So I do help them occasionally, but it's not out of any obligation, it's out of my own mercy. Personally I won't be having any children, so nobody will help me when I am old. I will likely be forced to die alone, or maybe I will die fighting in World War 3 or something, who knows.
Another idea that I think is social propaganda is that we have to contribute to society. However I don't think we owe society or the world anything by default. That said, the world doesn't owe us anything either. So I don't think we have any obligation to contribute to a society that doesn't give us anything back. In some countries it's a dog eat dog world with no support for the poor or low status individuals, while other countries are ruled by totalitarian elites and the people are exploited even more. I'm not sure why we should help the ruling classes of these societies, or those that support them, as they contribute to our own misery. I would just do the bare minimum to get by and not go out of my way to support such a society.
But personally in my European country, society has helped to provide for my needs when I was unable to do so myself. Therefore I am fine with helping my people, even if I don't like all of them. Through our society, they have had mercy on me, so I will have mercy on them and help where I can. Basically they fulfilled the social contract of this society, which is a good thing.
I do also believe we should generally follow the Golden Rule in individual interactions, which is to do unto others as we would have them do unto us. We are all fellow sufferers in this hellhole, and I think it is nice to ease the suffering of both ourselves and others when possible, within reason of course. That said, it is also practical because you are improving your own social reputation and decreasing the likelihood of confrontations that may be costly. However, you should still know when to say no and stand up for yourself as well. There is a time for everything.
