I already finished sending out applications a few months ago and, initially, I felt quite well about my main essay.
However, after watching some videos done by AO’s I’m losing a lot of confidence in the essay I provided.
Would anyone be willing to spare 5 or so minutes and read it?
Don’t second guess yourself now. Your essays are already in the hands of the ad coms. Take a deep breath and try to focus on other parts of your life. There is nothing you can do about your essays now.
Once you file your application you need to stop thinking about it. This process is difficult enough without you second guessing yourself. Move on.
My daughter second guessed her supplemental essay (after she was accepted!) She went back and reread it and laughed. I read it and could definitely see that her personality shined through. Trust the process. What is meant to be will be. Best wishes to you!
Move on and don’t worry about it.
I’m not a reader on these boards. But I will be happy to read it and find five things that are good about it. You do need to move on but maybe some positive feedback will help.
What’s done is done. Don’t overthink this. All you can do is focus on other things and learn from your mistakes. All the best!
Don’t worry so much about college applications! It’s only a small portion of your life. No matter what school you go to, I’m sure you’ll enjoy it there. 
Good luck!
