It takes time to overcome fatphobia, so it's a journey of patience and self-awareness. It begins by questioning the negative thoughts you have about your body size and replacing them with positive ones.
Also do away with negative people in your life and replace them with people that are supportive. You also need to talk nicely to yourself and learn to not pay attention to the shame that is imparted by society on plus size people. To fight fatphobia, it's not simple, but by returning to self-respect, it's doable.
