Scared of own parents?

[SorenVC]

Hi. I wanted to ask you guys for some help. I am 28 years old and I live in my 1 room apartment, it's cheap and it has everything I need. I only moved there about a year ago when I was 27. I work as maintenance mechanic.

But sometimes my parents judge me. I don't really interact with my father much anymore I just help him work on the house that they bought or he repairs my car and I help him. And my mother helps me with other things too but sometimes they judge me or put guilt and fear in me. I don't really know how to deal with them sometimes.

They just say stuff like "you're dumb" or "you're spending too much money on useless things, you're wasting your money" or "you're mentally ill" even though I'm always calm and easy to talk to. Am I supposed to just be calm all the time and take it? Cause that's what I am going to do lol.

I asked a friend from work and he said to just not care about it so much and it would be their problem since they are angry. My parents are just sometimes angry with my choices especially around money and they get angry at me. But it's my money and I'm 28 so can I not spend it?

And when I was young my father would shout at me for having bad grades. The grades didn't get better though. I just wanna ask you if my father or my mother suddenly become very angry at me or try to put shame and guilt on me, what should I do? Just be calm and ignore it? That's what I came up with. It works but inside it hurts sometimes what they can say.
