It took me until my 50s to stop being self-conscious about my slender body and skinny arms. Exercising more helped a bit but it was mostly in my head. My advice - love yourself now! (The sign was for a Twitter pro-nudity campaign)
20F, 5β4β, 155 lbs. this was at the beginning of my weight loss journey last year. Feeling really good about myself. Iβll post the progress pics later!
