How do i improve my looks?

Sorry. I don't have any pictures. Lately, I've just been feeling pretty ugly. I have acne, but not bad, and I bought some skin id to help with that. I mostly wear just mascara for makeup. But I think what I hate is that I have really chubby cheeks, that make my face look round and I have really ugly freckles. Also, I always have to wear my bangs up (I have side bangs) cuz they always split and fall half in my face. Another thing, I don't like smiling because I have crooked teeth. They aren't that bad but my 2 front teeth overlap. Idk if any of you will know how to fix that though because I think the only way might be braces. Anyways, what can I do to fix my appearance? How can I make my bangs stay where I want them? How can I make my cheeks less chubby? How can I try to get rid of freckles? And any other tips you may have? Please and thank you.
