i really wish i could just be comfortable with my body and happy in my own skin

i’m currently crying. i tried on an outfit and i told my mom i didn’t really like the way i looked in it. i asked her if i should wear it and she said i don’t want you to wear something you’re not comfortable in. how do i explain to her that it’s not my outfit. it’s on the inside. i don’t feel good in the skin i’m in. i don’t like my body. it’s my own skin that i’m not comfortable in. i’ve struggled with body image for so long and i just want to feel and look good. i know i can’t change the body that i’m in but i want to feel happy in it. it’s affected the clothes i wear and my style. i feel like i only look good in baggy t shirts. i want to be able to wear what i want to wear and what i think is cute. not just wont make me feel bad about myself
