Feeling inadequate nomatter how hard I try

I have been running an art account for 2 years and trying to post stuff on it but it's just inadequate and I only have 100 followers. I try to get good enough with SOMETHING enough to be known for it or to stand out SOMEHOW someway but does it pay off ever? No. If I was good enough I would have had a job and not been rejected. If I was good enough I would be able to pull the people I like. If I was good enough people wouldn't disrespect me and look down on me. If I was good enough people would put in the effort to get to know me and it wouldn't always be me needing to start conversations. Everyone is out of my league. I have nothing to offer to anyone ever. I feel so useless. I just find the next "person" or "thing" to obsess over bjt deep down I know they're too good for me all the time and all I ever do is bother them. They are busy out there succeeding and playing with the big dogs and I'm just insignificant and ant like in comparison. I can't keep up with anyone or provide enough for anyone to be of any use or substance that would cause anyone to want me.

   Nomatter how much I like an art piece I did nobody ever cares about it outside of a few friends. It doesn't matter anyways as A.I. will be the next thing and then what? My talent doesn't get me anywhere. My talent doesn't pay well. My talent is useless. Yeah ok cool I'm good at art but art isn't a necessity. Art isn't important. Nobody cares about a picture they'll look at for a few seconds then carry on their day with. In this world I feel I have to be so much to even mean the slightest to anyone or to be desired. I'm not wanted for anything but sex from men. Is that really how inadequate I am? Is that all I'm worth? Everyone has boyfriends and good jobs but I'm not even good enough for any jobs on my campus to select me even though I've applied to a few. I try my hardest but I'm too stupid and too slow to pick up on anything fast enough to be good enough to be noticed or admired for any skillset. Picking up a new talent would take me years so I wouldn't be good at it right away and I've been trying 3D modelling. With 3D modelling I just get stuck for hours on so much stuff and I look at all my other classmates post their 3D models for their assignments and they're so much better and put together. 

 Everyone else is so professional and proper and composed and I feel like I'm just this clumsy inadequate mess.  I feel so sloppy and mediocre. I'm not enough of anything to belong anywhere and I feel like I don't have anywhere to go. I don't have a "soulmate" or a "other half" romantically that everyone else talks about having. I don't have a group I belong to. I don't serve any importance or provide anything to anyone. This is why I'm afraid of meeting new people. I don't want anyone getting their expectations up with me or counting on me because I'll only disappoint them. It's just a matter of how long I can trail off the 1 thing I did luckily 1 time before they find out it isn't the default me. Nobody in my family wished me a happy birthday, only my friends and immediate family A.K.A. my mom and dad but otherwise no one else in the family bothered or cared to even text happy birthday.

Everyone else has this "special sauce" to them. I've heard a cousin talk to my grandma about how my grandma has this "special sauce" to her and people are just drawn to her effortlessly. It made me think on the fact that that's never been me. I don't have anything magnetic about me that people just "can't put their finger around" and that's also why I'm so frusterated. Why does the universe pick favorites? Why is it that some people are "effortlessly magnetic" and I can't even get anyone to care about my existence? I leave a mark on barely anyone's life when I compare how many people everyone else has. So many others have atleast 5 friends and a significant other.
