I am talking from experience, since my father died, everything he worked for, all his properties was taken over by those who despise him in the family when he was alive, since we have a very weird culture in the family we the children can't do anything about it.
I can literally relate to this since I didn't have a father an a early age, and I also have the same situation as my relatives split my father's allocated inheritance to all of my relatives leaving only a small plot of land that me and my 3 siblings have to cultivate. When I was young, our family was always taken advantage by our relatives (father side) since my mother doesn't have the power to retaliate given that her position isn't that well off in our household a lot common in an eastern household/tradition, and due to that some plots, harvests and even opportunity given are not passed down to us. I am the oldest grandson in my father's side, and the funny thing is that my father is also the oldest son on their family, but at that time that they are milking us all the benefits, they just immediately assume that I was young and underage at that time and I still don't have rights to complain, so for the sake of "management" they took the liberty of managing it on behalf of my father (blatantly scamming us). At the very young age I am already aware that they are milking me and my family, I also once confronted my grandmother and mother at that time, but they just couldn't help it. Although it felt bad at that time that it even reach to the point that I was even threatened by my uncle which is the brother of my father, now after so long, they no longer have the voice to speak in every family gatherings, in fact I am the one already dictating most of the family decisions now and even my grandmother's properties.
I was all aware this whole time while gritting my teeth and sucking my thumb not to take revenge but to be able to reverse the table where my odds are against. I know it's really hard, but on those times, I learnt to be independent, struggle as hard as I can, and be responsible for all the decisions I made. Now, I can gladly say that I have survived and will survived whatever comes.
To be honest when push comes to shove, there is no one ready to be there for you, there might be some but for sure they will have reasons not to fully help you, you'll just have to learn to live with this and struggle and I do really admit that one thing that really matters is to take care of yourself along the way.
