Will unfair or not?

[tryingtostickupforme]

I will start by saying I have name changed as I don't want to offend members of my family
I have had 30 years of mental health problems, but am considered high functioning so am capable of making my own decisions. Problem is when I do I am repeatedly shouted down by my family and told 'don't be so stupid' (when I have an opinion which differs from theirs). As a result I am now not sure if I am being reasonable or not. Please help me see....
I was a wild child for many years and certainly the black sheep of the family. I guess teenage rebellion didn't calm down until I was in my 30's (mental health mixed in). I am for the most part stable, however have been conned by men- in 2 serious relationships I have been financially abused (low self esteem and conned by a narc. For which I am still undergoing therapy, so please be nice). I admit I have never been great with money and my parents have bailed me out before now.
My brother is a high flyer and has never stepped a foot out of line. He is their golden boy and it has been made clear they feel like that from childhood. I understand he has put up with a lot of crap caused by me over the years. I love him as my brother, but pretty sure the feeling I not mutual. He tolerates me, but would rather I wasn't around.
My parents are currently setting up a trust fund for their will. It is being set up for my brothers 2 children, my brother and I, so a 25% split each way.
Am I unreasonable to think this is unfair? I have no children so they cannot be included, but my niece and nephew get 50% of my parents inheritance. My brother would be an executor along with a lawyer, so I would have no say, and even if I did, it would be 3 votes to 1. If it came down to a request later, my brother could (and probably would) decline it. He stands to gain with effectively 75% share and a vested interest in his children first.
I know it is my parents money and they can do what they want with it, but I feel I am being seen off in this. Am I being unreasonable or just ungrateful?

The money wouldn’t go into the trust fund

The house would be sold for care. Left over money is allocated specifically to others.

Anyway, OP, please don't subsidise your brother and his kids by providing care to avoid care home fees.
Surely the OP wouldn’t be ‘subsidising’ anyone? The money is her parents’ money until they pass away.
Sounds like they have been subsiding the OP for years, however.
I also also wonder maybe (pure speculation on my part) the OP’s parents don’t want her to care for them in their old age. We don’t know, but we can guess at their motives behind the will arrangements. Perhaps they also have a PoA so decisions on care won’t be the OP’s anyway. If they’re prudent enough to put this trust arrangement in place, I’d be surprised if they didn’t have one.
It sounds like things have been quite upsetting for her parents in the past and maybe they don’t want that drama around them into their old age?

Even if the OP is so lucky as to have parents that leave say £2M after all their costs, after inheritance tax is paid out divided by 4 beneficiaries this would be £332k each. Assuming a low risk annuity type investment max 5% per annum return would give her an income of £16k per annum. But this assumes SO many things - that there's going to be any money left, no big care costs etc. £16k per annum is half the av uk Household income....she should def hang onto her job, check her pension, Save a bit and claim any benefits that prevent or curtail her working ability while she's young. If the pot of money gets spent on stuff then of course the interest tumbles. I can see why the DB would be cautious.
