Hi pls. I need help. I came to stay with my grandm

Hi pls.
I need help.
I came to stay with my grandma for the holiday with my mum.
Since i came everyone has being giving me attitude.
So it happened i had a misunderstanding with someone that stays with us( not my relative)
I explained to my mum that i wasn’t liking the attitude i was getting and besides am older and I deserve a little respect.
I dont insult tho.
I even try buying stuffs at home for the two of us even when i just have little money.
Unfortunately for me my mum made it look like its my fault and saying i have a bad attitude and i don’t like accomodating people.
It hurts like hell.
Cause am an introvert and even with the fact I keep to myself I will never try hurting someone.
So it happened that the person got sick and i wanted to check online for a doctor to talk to and my mum called me from the room and i was just about sending the message to the doctor but i had to hurry to answer her since she called, on getting there my mum asked what i was doing i tried explaning to her that i was trying to consult a doctor and the next thing she told me is that i am a fool and my grandma also started insulting me calling me a mumu.
Well my grand mum was doing something and it fell so i told them am sorry and i was talking to a doctor and they kept on insulting me. I still helped her pick the stuffs that fell down.
This isnt the first time.
And am a very emotional person so i started crying.
Yeah i know people call me cry cry baby and all that.
But the truth is that i can’t do anything else.
And they all started insulting me the more.
It’s so sad that they get to embarrass me infront of this person.
And it’s so annoying even from the first day i visited i never felt at home.
I felt like i was a visitor.
If my grandma buys 3 oranges she gives two to that person and gives me only one.
She talks to me like am still a baby, i am in my first year in the university and will be clocking 20 very soon.
It makes me feel like am dull.
I can’t even talk to a guy on the phone without my grandma shouting ( just normal male friends).
I do all my best to be good.
I have been helping in the early morning chours without anyone asking me to do so.
I try my best to go on errands even when it isn’t me that suppose to run for errands.
I wash my mum’s clothes.
I try to engage in conversations with people around me just not to make them think am bad.
This was the same way i tried to please my cousins by taking them out, but after everything they lied to their mum that i starved them 😢 it hurts badly.
Like no one tries to see the good in me they only wait to see a little mistake i did and they are just all against me.
I tried telling my mum am sorry if i offended her and if it’s because of the person i argued with then am sorry.
But no she keeps giving attitude.
The attitudes dont get to me that much tho.
But the insults are very painful.
They never say anything positive about me.
I have vowed never to stay here again.
Am done with coming here.
I don’t just feel this place is really home.
Its like am a guest who have overstayed her welcome.
And i promise never to come back here.
I can try visiting them tho.
But not more that an hour.
I can’t even spend a night here.
I can’t even eat properly.
I think am having a mental breakdown.
I don’t want to die.
