body issues?

recently ive had such a hard time looking in the mirror...i am currently overweight but im working on it. the problem is even though other people tell me i look good and my bf obviously thinks i look great i look at myself and feel like i look bigger every day. i feel like my stomach just keeps getting fatter. i am 100% not pregnant and my clothing size hasnt gotten any bigger but i look in the mirror and see myself looking worse and worse. any advice to get out of my own head?
