I want freedom of speech, space and ownership

I hate staying with my mom.
I'm 30 yrs old for God's sake.
Why the fuck am I still staying with my mom?
Why the fuck am I not allowed to purchase my own flat, my own house?
I have enough $ in my CPF to downpay for a flat but I'm not eligible to because I am not married.
What the fuck is this.

I hate staying with my mom cause she stuffs the fridge with tonnes of food that are either expired or expiring.
I hate staying with my mom cause she washes clothes in 4 stages : Soaking, twice. Scrubbing, twice. Washing, twice. Spin, twice.
It's a waste of her time, our money, the earth's resources.
She simply cannot understand, despite our efforts to convince her for 10 yrs.
She thinks that she has put in so much effort but we do not appreciate.

I used to help her wash clothes a few times. She thought that those clothes I washed were not clean enough (for her standards) and she washed everything I washed, ALL OVER AGAIN.

She thinks she's the sole owner of the flat even though I have given her enough money I can pay for monthly instalments of a 3-room flat. I stopped giving her after I had to pay for several insurance policies. But I'm still paying for the telephone bills and her mobile line. My sis took over last year to pay for the utilities bills and housing loan.

We cannot criticise her. We get into endless arguments over the fridge of food that stayed/stays/will stay for a year or more. We get chided for not helping her and when we want to help, she dislikes it. She fears that we will dirty her space or things or whatever. She gets upset when we told her to save some money, for we are struggling with expenses and my fucking fiance cannot even earn enough to feed me alone.

She spends abt $1000 a mth on food and more food. Part of that money comes from the maintenance keeps my dad supplies her.
I suspect that she's suffering from mental breakdown which is causing her impulse buying behaviour. I don't even spend $500 a mth on buying.

But I pray and hope she's fine and healthy and will leave me alone when I finally get married and move out one day.

I love her.
But I cannot stand living with her if she's gonna waste water, electricity, money and boss me around.

I stay in this house but I have no say, no freedom, no respect.

I'm 30 years old. I cannot wait to leave this house, if better still, this country.
