Hey, its OK. SJs are just really really high maintenance. It may be that the only reason your mom is acting out in the way she is is because she isn't sure how you feel about her.. at least this would be my mom's reasons.
I have an ESTJ mother so I can seriously relate to most of the stuff you are sayin' (except for not being able to make macaroni, come ON woman
)
Usually its easier for me to get upset with my mom, look for someone to agree with me that the woman is borderline insane but I know that really doesn't help. You don't get to pick your parents and no matter how difficult they may be, you should love them anyway.
You don't have to agree with anything she says but you shouldn't argue with her either. I find it easier to just say "OK" to whatever silly thing my mother is accussing me of (somehow this works???) And when I disagree with her or I feel she has done something to upset me I voice my opinion, but I never let it turn into an argument. When you argue with an SJ parent....you lose.
I'm glad that you see some good in your ma though, just remember she may be scared that you will be leaving soon, who knows. Once you get your independence things should definitely get easier for the two of you.
