i hate and love my body

hii guys i’m 14 and i’m 5’5 105 lbs . i’ve always disliked my body because how skinny i am. but i have finally gained the confidence and love my body for what it is. i just want to stay this way, my dad calls my skinny, but my mom calls me perfect. so im trying to gain weight, but i cant because of my metabolism🥺.
