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)
21, 5’0, 130lbs - I’ve spent about a decade struggling with disordered eating. A year ago I weight 110lbs. The change has been difficult, but I’m learning to love it.
