^^^ like he said. You don't deal with them. You ride the roller coaster. For people like us it can be a complete nightmare. Especially if they find out you have AS, or anything else they can pick away at. Keep to yourself as much as you can. Be an emotionless robot. Don't get emotional, or excited. AT ALL!! ! if anything effects you for any reason she can find, it will be a target for her narcissistic supply.
