(27F, 5'6'', 125 lbs). I went from the happiest I'd ever been to a breakup and my lowest low in just a few weeks. Honestly I really could just use some love and validation right now.
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)
