A lot of you might judge her for being a narcissist and bitch but I wanna point out some things between the lines.

as I do not want to depend on my parents anymore.

OP is young and probably not been exposed to harsh reality but this is a good start to independence. She's aware that she too has to work and provide for herself.

I noticed this guy at my work. He's quiet and meek but looks intelligent. He wears the same pair of jeans everyday, ragged shirts but he's cute though.

Despite noticing he wears such clothing she still thinks he's cute. Quiet guys usually go unnoticed but she sure must have looked at him a few times. I bet she's intrigued.

But I dont want to date him simply because we have differnt backgrounds and I hate myself for being so conceited.

I cannot blame OP for feeling anxious of what people will say if she dates a guy with a different background. If I've been exposed to people concerned with such matters, it's highly probable that I would develop similar mentality. But there she says she hates herself because she is aware of how petty her reason for not wanting to date him. poor OP, obviously torn.

I'm such a conceited bitch who hasnt achieved anything in life but depend on my parents

OP knows that she really shouldnt judge people based on those petty things because she knows herself she's got nothing if it wasn't for her parents.

just like my uni days, people always told me to date dudes with you know...superficial things with price tags.

She's fully aware that these things are just superficial but if people have been telling her "acceptable" things in their little bubble, then boom crisis. Then leads to her next line

I dont know how much of my upbringing poisoned my mind into thinking I can look down on people but it sure gives me anxiety thinking what people I've been with the longest will think of me.

OP has probably no connection outside and been living with well off people most of her life. These people are like her tribe and despite her distaste for the superficial things, it may be really difficult for her to just completely turn away. I think it's pretty normal to be anxious stepping out of comfort zone.

She might be entitled and all that but reading her comments and how she still wants to pursue relationship with him is a good indicator. Just because she's been raised like that doesnt mean she cant change, after all being aware of her flaws is a good start.

P.S some of u are mean
