'I do this for your good.' Can I just lash out on him?

Says all bullshit stuff like "wouldn't bat an eye if you died" for my OWN GOOD i suppose.

This is gonna be long.

My dad and mom have been going for their morning walk. For the past few days, all she has been hearing are tantrums from him.

"They don't sit near me anymore"

"They treat me like an enemy"

"They used to be so bright earlier"

"I'm the roof of the house, when I die, no one will even come to ask how you all are doing."

SIR, stop. The time when me and my brother used to be all cheerful and bright was the time when you were not here living with us and ruining our days, while at the same time expecting us to heal you or become therapists for you.

He is the same man who talks shit about his whole family to one of the distant relatives whom he is very attached to. And honestly, that distant relative is a pain in ass. That man, the distant relative, lives with us and wants to know everything, he's in his 30s and wants to be carried by my mother and us wherever we go. Want us to treat him like he's some special person and if he's not here we'd die, or atleast that's what my father thinks. And now these days, that distant relative is not very talkative to my dad because of which he's losing it and is having all these random childish moments.

One time my dad called all of us to his room to give us t-shirts he got as a gift and it was very large for my size, my mom was going to grab the shirt to place it on my back to check the size and THIS RELATIVE grabbed it before and if you're familiar with this technique or whatever way this is to check size, you'll know that you don't have to have your whole hand on the person's shoulder and below right? This man right here, put his whole hand, it was touching below my collar bones. You just know if it's a good touch or a bad one. It was the second definitely. And it's not the first time I've felt this uncomfortable with that relative. And when i shook his hands away in disgust you know what my dad said,

"Why are you getting angry?"

As if i shouldn't be angry.

Even my mom was like "tf you saying to your daughter, you should be taking her side". She didn't say it but yes, later she said this to me.

And he does it for my own 'good'?

The same man who pressured me the WHOLE year to get 90+ in my boards, saying all the bullshit that he usually says, taking out his random anger moments on me is the man who is now saying,

"It's not gonna do anything. Just because you got 97, you don't have the right to act as if you got a crown or something."

First of all, no one wants his acknowledgement. Second of all, according to me, that shitty response is DEFINITELY not what I deserve after the whole year of his nonsense.

I've been asking for a tablet for YEARS now and every time there is a 'financial problem'. It's ONLY when I want something, otherwise they have all the money to spend it on useless stuff and regret it afterwards. But when I want something, that REALLY can help me, it's suddenly "you won't focus on your studies then, you'll be on your tab all day"

Please, i was not even acknowledged and honestly it's not something i expect. But I also don't expect my hard work to be treated like garbage.

What can I do in this situation. Like not in a long term, but right now.
