Learning to see people as equals

When I was in elementary I would literally be friendly and be friends with my classmates because I see them as equals regardless of whether they are smart or rich. what I was afraid of or I didn't see as equals was those who are a grade older than me so I felt inferior to those that are older than me. Now that I'm in college, I notice how I can speak to those that are older to me now, I don't care about their age and if they are a year older than me, I can literally have a normal conversation with someone who is 50 years old and feel equal to them. What I am now insecure about is with people's status or if they are richer and stylish than me, or are smarter than me. Because even when we haven't spoken to each other, I immediately generalized them into this personality that they look down on people and aren't humble I mean I could notice that some of them are and I am afraid of those kinds of people because who wants to feel lowly and inferior? also, I am a middle class and I can afford only everything that I need and if I want something, I need to work for it or we have to wait before I can have that thing. or they don't even have to be the "they look down on people and aren't humble" I will still be insecure of them even when they are kind people because I can see that their friends are also rich and I feel like we won't have the same interest and I wouldn't fit into their lifestyle. I realized that maybe I am afraid of these people because my ego gets hurt if I felt inferior or when people look down on me or when people think that they can be rude or mean to be because they feel that I am inferior to them. Deep inside, I just want them to see me as equal. Someone they can vibe with but also someone that they know they wouldn't disrespect. I have experienced these types of scenarios thats why I have this fear. But now I want to be able to overcome it. I question myself that maybe there is a characteristic of me that makes them look down on me. Maybe because my jokes can be corny or something? Or maybe it is my vibe? is it the way I dress? But I think it's with the way I dress. I am obese, and I wear large T-shirts that are below my butt and I do not have hips or butt even though I am big so I look like older. And I am insecure of my body. I do not know how to style myself. But it's not about the looks. I have a schoolmate who is bigger, is not attractive too but people like her. She has a good personality, she's witty, and smart. And so my constant wondering of what is wrong with me never ends. Now what I want is to remove this insecurity. Once I have overcome this, I know that I can finally be confident and be able to speak to anyone. Because these are the types of people I need to be socializing with because I want to be successful and they are most likely the people that are going to succeed too and overall I just don't want to be scared of certain people. I want to be able to just be normal with them. and just see people as normal people like me who takes a shit, farts, and have diarrhea sometimes. I want to be able to talk to people whether they are the president or the vice president or are smart or are serious and whatever it is. And I also want to become the type of person that they too see as equal whatever my status is. does this makes sense? I don't know, I don't want to revise it.
