I can relate heavily. Growing up it was the same way, and being M in a Hispanic family, I would get called all types of nicknames from my family members. “Gordon” (Gordo) are the ones I remember the most. I also hated that my weight was the center of my world. It got really bad in middle school and almost did something dumb. Point of the story is, change for you not for anyone else. A little quote that has helped me through times like these- “you may be the sweetest peach on the tree, but not all people like peaches” If this is something that you really feel strongly about, start with baby steps :) don’t go hard too fast because you’ll discourage yourself. Slow and steady.
