1 and 2 require commas. It then becomes an apposition that explains the subject "everyone" better. Three should be a dot with a capital letter on Y while 4 should be a comma as well to separate clauses.

So the sentence will have to be like this: Everyone, aside from mom and dad always looked at me strangely because of my scars. You'd think they'd never seen anything like it before or that it would somehow rub off on them.
