I have a particular insecurity...?

okay so a lot of people have like one thing they hate, like their nose or their feet or somethingg, but im like overweight, like pretty overweight like obese. i wear like juniors l-xl but im only 5 foot and done growing. also i go to a nutritionist, the gym, and i do high school cheerleading. i thinks its really embaring when i have to wear the little outfits with the rest of the team but i do it because i love cheerleading. and also i feel like people are so shallow and i wont get a boyfriend all through highschool. im not bragging lol but i am pretty and have a great personality but anyway does anyone have any experiences when they have a similar situation to mine that thye could please share with me, i would love to hear ur stories! thanks so much sorry i complained so much lol
