21F, 75 kg, 152 cm. I received a lot of lovely comments and messages, telling me that I should love my body after my previous posts. Thank you so much for these people. I wish all the best for you.
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)
