When you are sick, you need to surround yourself with positive supportive people. They will help you and support you and encourage you to do anything you need to do to get well.
I'm sorry, but your mom sounds rather negative. I would not take what she says to heart. Maybe she's more concerned with "what will the neighbors think?" than your health. Or maybe she has her own issues, I really don't know.
Whatever you do, you must put yourself first when you are sick and do everything you can to get well, no matter what anyone thinks.
