unhappy with my body and would like some help and advice

Kristine
So I'm a 178 lb 5'4 18 year old. I am in a happy relationship and my boyfriend says he loves me but sometimes I feel strange because he is a fit 6'1 male that lifts and is in great shape. I would like some honest and possibly helpful advice for loosing weight and maybe not even weight, but inches?? This is me now I'm a couple of photos. Some next to my boyfriend
