Ven Johann,
as for now, i had the chance to reflect on the relationship and find some of my errors. I also reconsidered the role of parents and their burden. For so, there is a big debt.
Anyway the debt can be extinguished. For example, when a parent harrasses for half life, deprives of heritage, abuses, because of arrogance and stupidity, a big debt can eventually be extinguished, or there can even be a credit.
I gave help, but i'm still convinced i have no debt left, and more, i could even be in credit, expecially by having not taken strong countermeasures to defend myself properly. Actually i consider this could be the case, i have (had) a parent with a debt toward my person.
Why this question?
Thank you

Again, no, Nyom

There is no such as an ideal, similar of what people agree "this is poor and serves help"
The goodness remains given goodness, what one has taken, received. This is why one is capable to develop the Brahma Viharas toward all being, since hardly a being can be found that was not one father, mother. And it has to begin with the first Gods.
It's also not so that there is such as a universal account that one has to bring to zero, for such is impossible.
By ending of craving, stopping of taking on everything, debtlessness is reached, eg. Arahat ship.
If thinking in ways like " I have given back enough", one does not only open up all ways of denying goodness, but develops also hardly Samvega, goes on to incease indebting, taking on anew.
And again, even the conventional debts toward parents, as the Buddha stated, could not be returned by giving all wealth, all services, but just by assisting them toward non-greed, Sila ...
Practice, again, does not seek to balance wander on, but to develop all goodness supportive to be able to leave. The focus is on goodness. At least, what isn't taken from others, of which Nyom could return? How could he give back the assistance he received as he was total helpless, just seeked to take on things, gain birth. Nobody else did give at that point aside of the own parents.
One who eventually sees the whole worlds caught in debt, Samvega, develops care about every being. But such isn't possible if not strong seeing the duty of taking care about one's Gods at first place, still carry notions of wrong view "I have/had a right".
