I still can't take my mask off because of the cold

I'm a first-year high school student born in 2008, and I had to wear a mask for 6 years because of my wide nose and protruding teeth. (I went through puberty in 4th grade,
 
so I continued to wear it even before the COVID-19 period.) Until 5th grade, I took off my mask when eating lunch. Then, after the boys teased me about my nose a lot, I never took it off until middle school except for when I took graduation photos.
 
 I feel sorry for the first-year students who suffered from COVID-19, but I was really happy when COVID-19 broke out. I wasn't sick until 2020, but people treated me like a weirdo if I wore a mask. I even had counseling when I was in elementary school because of this. I think I was really obsessed with my appearance since then.
 
Anyway, I need to get braces on my mouth, so I put it on hold and just wanted to do something about my nose, so I saved up about 200, but my parents absolutely won't allow it. What should I do? If I can, I want to get cartilage binding and nose tip reduction during winter vacation, and if that doesn't work, I want to get something like petit nose filler. Ha...
 
When I received counseling in the open chatroom, I heard a lot of people say things like, "Study hard and go to college and tune up later. Who cares so much about you that you can't take off your mask the whole time you go to school?" I know, I know, that's the normal way. But I had looks sickness since I was in 5th grade, and since then I've been losing my hair, and I'd cry and vomit every night, so my height stopped at 162. Even though I didn't do anything particularly bad, I never ate school lunches, so my weight has never exceeded 41 kg.
 
If I had been ugly even when wearing a mask, I wouldn't have had looks sickness, but my forehead, eyes, and face shape are fine, so I'm a typical magician. So when I remember the kids' reactions when I graduated from elementary and middle school, I'm so sad and miserable. I thought I was a magician because I was so picky about wearing a mask, but they asked me if I was usually so pretty and had a black nose and mouth. It's so strange... In middle school, I went to school like I was dead after graduating from
 high school
. That's how it was in high school. I came to a place that takes 50 minutes to commute by bus, but it's no different from my previous life. I've already given up on
 my subjects. I was talented in arts and physical education like music and physical education in elementary school, but since I have to wear a mask, my grades are always low in performance and the last time I ate lunch was in 5th grade. I wonder what school lunch tastes like.. My friend is kind and I'm grateful that I've become friends with good friends like me, but what if they play a prank by taking off my mask whenever we hang out? If they see me without my mask, they'll throw it away anyway, so I might as well cut it off now instead of getting hurt then.
 
The most miserable thing is that my school sends first-year students on a school trip in early May, but out of all the first-year students, I was the only one who didn't go. Thinking about living in high school for two more years like this
 
makes my future dark. If you've read this far, I'm going to feel really pathetic. I'm
 sorry for writing all about my life story and depressing stories.
 I'm not the only one here who's struggling, but I'm the one who's There are quite a few common people, but I hope that after reading my story, you will find comfort in thinking, “Oh, there are people like this, and I’m lucky that I’m better off.”
