In every picture I take my face appears crooked, particularly my eyes. Why is this? Is it just my bone structure? (Photo)

I've noticed over the last few years in every picture I take my face,particularly my eyes, appear crooked (for lack of better terms). It is really starting to make me feel self conscious. is it just my bone structure or are my eyes drooping or what? My best friend swears I don't look like that in person but now I'm noticing it in the mirror not just pictures.
