Ohmy.
Well, as for your aunt, is it a permanent move? "Staying here" implies just a visit, and if such is so, then perhaps it won't be for long. It will take adjusting, of course, but things will return to normal once more eventually.
Otherwise, dear, rarely is it easy to deal with the views of others. But what is truly important is how you view yourself. If you're secure with your own reflection, you really shouldn't mind all that much what others make of it (Outside of constructive comments, of course). Are you comfortable with and do you respect yourself?
