Hi 9589slw!
I can assure you that nobody around you has the perfect body, because there isn't one!
But I understand what you are experiencing; it is really hard to feel like our bodies are ok, let alone beautiful.
All our bodies are amazing feats of nature, it's just difficult to see it ourselves sometimes. I know for me, the wider situation helps. If I'm feeling stressed about other things then I'm not going to feel great about my body. So is there anything going on at the moment that might make you feel down on yourself in general?
I also take care of who I follow on social media, and other media I consume. If it's full of people focusing on a certain type of appearance making me feel bad, I can unfollow, unfollow, unfollow.
Also, it's worth asking, what situations and media DO make you feel good?
I have this to recommend from us:
The Sex Goddess Blues: Building Sexual Confidence, Busting Perfectionism
I know it's about sexual confidence, rather than general body confidence but the words (and those amazing illustrations!) could be helpful.
