Girl just gimme some advice


so I'm hella body conscious and it stops me all the time from doing things I'd love to do such as swimming and honestly wearing cute ass clothes. I've got a lot of friends who tell me I've got nothing to worry about but it still bothers me all the time. I'm currently 5'7" 17 and 165 pounds. What do y'all think I should do? or do y'all have advice on learning to love my body a bit more
