Little sad

I've always been seen as skinny. Always. And I am, I got it from my dad who looks like a living beanpole. As a woman this has always been little awkward because no jeans fit me. As I got into high school I started running, gaining muscle and things but my arms are still awkwardly tiny. With this, I've always had this little belly, it looks so awkward on my skin and bone body. I've struggled with a lot of self hate in the past, I'm trying to love myself. So I wanted to ask what you guys think. Is my stomach gross? Noticeable? If I try I can shrink it but it's been really hard for me to get over this flaw that I tell myself I have.
