I am now embarrassed to wear a bikini. Pic ?

I'm alittle smaller than this in person , the way the pic was took just made me seem a bit bigger. But I'm about 5'4 in height and I weigh 120-122 pounds ( it moves between there ) . I'm a healthy weight but I'd like to waist train. I want a more defined toned stomach. I just feel like I'm to big.. And I've became quite insecure. I'm 17 if that helps
