Can anyone please give 建议 on this?

Don't worry my dear, I have never been able to blend in the boring society. Most of the teens are so alike, they all dress in "trendy" clothes, have the same interests, standards of what's considered beautiful (about looks and body). 你 are not worse than others, 你 are just different, it could take time to realize it, but don't blend in, don't try to become like everyone, it's wonderful that 你 have your uniqueness. 你 are beautiful, maybe not beautiful like they, but beautiful in your own way, maybe your way is even 更多 beautiful than theirs? Think about it. Maybe 你 can't appreciate it now but one 日 你 will realize how priceless your uniqueness actually is. Trust me.

First of all, being satisfied with yourself is what's important. How others see 你 is of no importance compared to that. If 你 want to feel better about your style, change it according to your preferences. Concerning your clothing attire, experiment and stick with whatever makes 你 feel better. As for your physical appearance, a healthy lifestyle is the way to go. Eating properly and exercising will eventually go a long way. Finally, attractiveness can be a subjective matter. Not everyone shares the same standards. Having 更多 confidence in yourself will boost your perception 由 others !!!!

i feel the same way dont worry. ur not alone.

Start looking at them 更多 and think less about how 你 look.
Crank up your pervertedness.

Do what I did when I was in high school and stop caring about what people think. It's honestly how I became one of the most liked guys there. Both guys and girls 爱情 confidence in someone. They respect 你 for it. On the night of my senior prom, I proved to be the 秒 best dancer. I was good enough to rival a dance major. We even had a dance off. I 迷失 of course but lots of people respected me and even had crushes on me after seeing how I could 摇摆, 秋千 my hips to the beat. It was my first time too. I went in, scared of dancing in front of all those people but I decided that I didn't care what they thought and did so anyway. Everyone wanted to dance with me. Had one girl who kept pulling me to the side when I was dancing with other people. It was the best night of my life. The moral of my story is to not let anyone stop 你 from being amazing. 你 got this shit. Just because you're not me, doesn't mean 你 can't be awesome! In this club, you're surrounded 由 tons of awesome people. Lefteris, Zanny, Mauser, Legend, DisneyPrince88, Nomy, Riku..... I could go on and on, my friend. We're your 老友记 and we like 你 for who 你 are! You're awesome!

The easier solution would be to stop caring about all of this stuff and try to realise that no matter how perfect somebody may seem, they still probably have tons of problems they are going through that 你 just don`t notice and don`t know about.
On the other hand, not so easy, but a bit 更多 helpful solution would be to analyze step 由 step what are the exact things that 你 don`t think 你 have, but everybody else does and make a plan how to achieve that. Working out, healthy meal plan, some other daily activities etc. (And about the clothes I think it`s most important to find out what fits exactly 你 and your shape, not to see what others are wearing)

It's only natural to compare yourself to others, especially in a school environment.

你 just have to focus on yourself and put out to the world the best that 你 can. If you're unhappy with your presentation, research into fashion. It doesn't need to be expensive and labelled, 你 can look damn nice dressed in cheaper clothes. Find a style 你 like, express yourself through it.

If you're unhappy with your physical shape, get into fitness :) 加入 a sports team 或者 if you're shy to interact then 加入 a gym. If 你 don't have the funds for a gym, YouTube basic workouts and 你 can exercise while watching the vid. Watch what 你 eat, don't eat lots of 破烂, 垃圾 food. Drink lotssss of water. 2 to 3 litres. Water improves your skin complexion and hydration. No sodas.

A lot in terms of physical attractiveness can be enhanced 由 exercise and diet. I'm not much of a believer in enabling bad habits to not hurt feelings. I'm a strong believer in putting in the effort to get the rewards. 你 can do it :)
