Advice please??

Hey ladies I’m in need for advice. I’m 16 I weigh 133 I’m 5’5 and I’m super self conscious. I feel like I’m fat and I want to look like those models who have the perfect body. I’m going to the beach next weekend and I’m afraid to wear a bathing suit. My boobs aren’t that big either which also makes me self conscious of what I wear and I just can’t seem to feel ok about my self 😕
